+//! In this example we will connect to a parachain and subscribe to its blocks.
+//! There are many parachains on Polkadot and Kusama. In order to connect to a
+//! chain we first need to fetch its metadata. This requires us to know a valid
+//! RPC endpoint of the chain.
+//! The [Substrate Chains Runtime Api Doc Center](https://substrate.rs/index.html) lists parachains
+//! on Polkadot and Kusama and gives us a list of RPC endpoints for each parachain. Alternatively
+//! we can also look for the RPC endpoint of a chain via [Polkadot.js](https://polkadot.js.org/apps/).
+//! In the side menu, you can select a Polkadot/Kusama parachain. The hit the "Switch" button and
+//! let the page load the chains data. The RPC endpoint url can be found as part of the url.
+//! You can also open the console, to see the RPC endpoint url printed without URL-encoded special characters.
+//!
+//! Let's go through an example for the "Ajuna" parachain on Polkadot.
+//! Selecting it in the [Polkadot.js](https://polkadot.js.org/apps/) menu, then opening the console
+//! lets us observe the following output: `WS endpoint= wss://rpc-parachain.ajuna.network`
+//!
+//! We can now get the metadata of the chain via the subxt-cli tool.
+//! It is important to note that we need to add a `:433` as the port number here:
+//! ```txt
+//! metadata --url wss://rpc-parachain.ajuna.network:443 > artifacts/ajuna_metadata.scale
+//! ```
+//!
+//! This allows us to construct a module with the ajuna types, calls,
+//!
+//!
+
+use subxt::{Config, OnlineClient, PolkadotConfig, SubstrateConfig};
+
+
+/// Default set of commonly used types by Polkadot nodes.
+pub enum AjunaConfig {}
+
+impl Config for AjunaConfig {
+    type Index = <SubstrateConfig as Config>::Index;
+    type Hash = <SubstrateConfig as Config>::Hash;
+    type AccountId = <SubstrateConfig as Config>::AccountId;
+    type Address = <SubstrateConfig as Config>::Address;
+    type Signature = <SubstrateConfig as Config>::Signature;
+    type Hasher = <SubstrateConfig as Config>::Hasher;
+    type Header = <SubstrateConfig as Config>::Header;
+    type ExtrinsicParams = <SubstrateConfig as Config>::ExtrinsicParams;
+}
+
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error>> {
+    // Create a new API client, configured to talk to Polkadot nodes.
+    let api = OnlineClient::<AjunaConfig>::new().await?;
+
+    Ok(())
+}

+//! # Connecting to a parachain with Subxt
+//!
+//! In this example we connect to a parachain and subscribe to its blocks.
+//! There are many parachains on Polkadot and Kusama. Connecting to a parachain (or any other substrate based blockchain) with subxt requires 2 steps:
+//!
+//! 1. Fetching the chains metadata to generate a static interface via the subxt codegen.
+//! 2. Creating a config struct that implements `subxt::Config` to give some type information
+//! that is currently not covered by the metadata.
+//!
+//! We now show these steps in detail. As an example we use the
+//! ["Statemint"](https://parachains.info/details/statemint) parachain, also known as "Asset Hub" that is currently (2023-06-26)
+//! deployed on Polkadot and [Kusama (as "Statemine")](https://parachains.info/details/statemine).
+//!
+//!
+//! ## 1. Fetch the Metadata
+//!
+//! To fetch the metadata for the Statemint parachain, we need to have the URL of an RPC node.
+//! We can find the "Asset Hub" entry, by looking through the sidebar on [Polkadot.js](https://polkadot.js.org/apps/).
+//! We connect to the node ("via Parity"), which leads us to [this page](https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Fpolkadot-asset-hub-rpc.polkadot.io#/explorer).
+//! In the URL of the page we can already see the URL of the RPC endpoint of the node as a query parameter. It is also printed
+//! to the Javascript console of the browser: `WS endpoint= wss://polkadot-asset-hub-rpc.polkadot.io`.
+//!
+//! Let's create a separate crate for the statically generated interface.
+//! Keeping the metadata and the resulting generated code in a separate crate
+//! avoids unnecessary recompiles, whenever you change something in the rest of your project.
+//!
+//! ```txt
+//! cargo new metadata --lib
+//! ```
+//!
+//! In the new crate we can now get the metadata via the [subxt cli](https://crates.io/crates/subxt-cli) tool.
+//! It is important to specify the port as `:443` like so:
+//! ```txt
+//! subxt metadata  --url wss://polkadot-asset-hub-rpc.polkadot.io:443 > statemint_metadata.scale
+//! ```
+//! The metadata is saved as `statemint_metadata.scale`. We need to add subxt as a dependency with `cargo add subxt`
+//! and then we can replace the code in lib.rs with the following:
+//! ```
+//! #[subxt::subxt(runtime_metadata_path = "statemint_metadata.scale")]
+//! pub mod statemint {}
+//! ```
+//! We use the `metadata` crate as a dependency in our main project and have access to
+//! all the pallets and calls of Ajuna via the exported module `metadata::statemint`.
+//!
+//! # 2. Create the Config
+//!
+//! To construct a config, we need to investigate which types Statemint uses as `AccountId`, `Hasher`, etc.
+//! We need to take a look at the source code of Statemint and find out how it implements some substrate functionalities.
+//! Statemint (Polkadot Asset Hub) is part of the [Cumulus Github repository](https://github.com/paritytech/cumulus).
+//! The crate defining the parachains runtime can be found [here](https://github.com/paritytech/cumulus/tree/master/parachains/runtimes/assets/asset-hub-polkadot).
+//!
+//! ### AccountId, Index, Hash, Hasher and Header
+//! We need to check, where the parachains runtime implements the frame_system::Config trait.
+//! Look for a code fragment like `impl frame_system::Config for Runtime { ... }` In the source code.
+//! For Statemint we find it [here](https://github.com/paritytech/cumulus/tree/master/parachains/runtimes/assets/asset-hub-polkadot/src/lib.rs#L179).
+//! The `AccountId`, `Index`, `Hash` and `Header` types of the [frame_system::Config] should also be the ones
+//! we want to use for implementing [subxt::Config].
+//! In the Case of Statemint (Asset Hub) they are:
+//!
+//! - AccountId: [sp_core::crypto::AccountId32]
+//! - Index: [u32]
+//! - Hash: [sp_core::H256]
+//! - Hasher (type `Hashing` in [frame_system::Config]): [sp_runtime::traits::BlakeTwo256]
+//! - Header: [sp_runtime::generic::Header<u32, sp_runtime::traits::BlakeTwo256>](sp_runtime::generic::Header)
+//!
+//! ### Address, Signature, ExtrinsicParams
+//! A Substrate runtime is typically constructed by using the [frame_support::construct_runtime] macro.
+//! In this macro, we need to specify the type of an `UncheckedExtrinsic`. Most of the time, the `UncheckedExtrinsic` will be of the type
+//! [sp_runtime::generic::UncheckedExtrinsic<Address, RuntimeCall, Signature, SignedExtra>](sp_runtime::generic::UncheckedExtrinsic).
+//! The generic parameters `Address` and `Signature` specified when declaring the `UncheckedExtrinsic` type
+//! are the types for `Address` and `Signature` we should use when implementing the [subxt::Config] trait.
+//! In case of Statemint (Polkadot Asset Hub) we see the following types being used in `UncheckedExtrinsic`:
+//!
+//! - Address: [sp_runtime::MultiAddress<Self::AccountId, ()>](sp_runtime::MultiAddress)
+//! - Signature: [sp_runtime::MultiSignature]
+//!
+//! #### ExtrinsicParams
+//! The `ExtrinsicParams` type is the most complicated to set up, but it can be derived from
+//! the `SignedExtra` parameter of the `UncheckedExtrinsic` of your parachain. The `SignedExtra` parameter is a tuple in most cases,
+//! where each field of the tuple corresponds to 0-1 fields in the `ExtrinsicParams` struct we want to create.
+//! It looks like [this](https://github.com/paritytech/cumulus/tree/master/parachains/runtimes/assets/asset-hub-polkadot/src/lib.rs#L779) for the Statemint parachain:
+//!
+//! ```rs
+//! pub type SignedExtra = (
+//!	    frame_system::CheckNonZeroSender<Runtime>,
+//!	    frame_system::CheckSpecVersion<Runtime>,
+//!	    frame_system::CheckTxVersion<Runtime>,
+//!	    frame_system::CheckGenesis<Runtime>,
+//!	    frame_system::CheckEra<Runtime>,
+//!	    frame_system::CheckNonce<Runtime>,
+//!	    frame_system::CheckWeight<Runtime>,
+//!	    pallet_asset_tx_payment::ChargeAssetTxPayment<Runtime>,
+//! );
+//! ```
+//!
+//! The `ExtrinsicParams` struct is basically a collection of fields that can be grouped into two categories:
+//! _extra parameters_ and _additional parameters_. _Extra parameters_ are taken into account when
+//! signing a transaction and sent along with it, while _additional parameters_ are only used during
+//! the signing step but _not_ sent along with the transaction.
+//!
+//! Each element of the `SignedExtra` tuple implements [parity_scale_codec::codec::Encode] and [sp_runtime::traits::SignedExtension]
+//! which has an associated type `AdditionalSigned` that also implements [parity_scale_codec::codec::Encode]. Let's look at the underlying types for each tuple element.
+//! All zero-sized types have been replaced by `()` for simplicity.
+//!
+//! | tuple element                        | struct type                                     | `AdditionalSigned` type          |
+//! | ------------------------------------ | ----------------------------------------------- | ---------------------------------|
+//! | [frame_system::CheckNonZeroSender]   | ()                                              | ()                               |
+//! | [frame_system::CheckSpecVersion]     | ()                                              | [u32]                            |
+//! | [frame_system::CheckTxVersion]       | ()                                              | [u32]                            |
+//! | [frame_system::CheckGenesis]         | ()                                              | `Config::Hash` = [sp_core::H256] |
+//! | [frame_system::CheckMortality]       | [sp_runtime::generic::Era]                      | `Config::Hash` = [sp_core::H256] |
+//! | [frame_system::CheckNonce]           | [Config::Index] = [u32]                         | ()                               |
+//! | [frame_system::CheckWeight]          | ()                                              | ()                               |
+//! | [frame_system::ChargeAssetTxPayment] | [pallet_asset_tx_payment::ChargeAssetTxPayment] | ()                               |
+//!
+//! All types in the `struct type` column make up our _extra parameters_.
+//! We can put them together into a struct, ignoring all zero-sized types.
+//! The types of the last column make up our _additional parameters_. Here
+//! we can also ignore the zero-sized types. We can name the fields however we like,
+//! however their order in the struct should match the order in the `SignedExtra` tuple (see table).
+//! Beware that some numbers might be compact encoded, when encoding the struct, some might not be.
+//! Please check the exact struct type definition here. For example the definition for CheckNonce is
+//! `CheckNonce<T: Config>(#[codec(compact)] pub T::Index)`. We can see that the `#[codec(compact)`
+//! attribute tells us that the `u32` value needs to be compact encoded.
+//!
+//! Because the `pallet_asset_tx_payment::ChargeAssetTxPayment<Runtime>` struct requires us to pass the
+//! struct of our `Runtime` as a generic argument, we decide to just recreate the struct here. This prohibits us
+//! from pulling in tons of unneeded dependencies. This is a pattern that you might see often,
+//! especially because substrate crates and their types are quite big, clunky and entangled sometimes.
+//!
+//! With all these types collected, we can create two structs: `StatemintExtraParams` and `StatemintAdditionalParams`.
+//! Then we combine them into a `StatemintExtrinsicParams` struct for which we implement the [subxt::config::ExtrinsicParams] trait, see below.
+//! Now we have all the parts we need to create our config `StatemintConfig` and implment the [subxt::Config] trait on it.
+//! Note that StatemintConfig is an empty enum, an _uninhabited type_ that is never means to be instantiated
+//! but just gives type information to various interfaces of subxt.
+//!
+//! # 3. Simplifying the config
+//!
+//! Now you should be able to create a config for a parachain from scratch and understand the details of its construction.
+//! However this is quite a tedious process, so subxt provides some sane defaults that can make your life easier.
+//! First, let's ditch the dependencies to [sp_core] and [sp_runtime].
+//! We should not be forced to utilize these traits whenever we create a config for a chain.
+//! That is why subxt provides some types that can function as drop in replacements for some types in [sp_core] and [sp_runtime].
+//! You can use:
+//! - [subxt::config::extrinsic_params::Era] instead of [sp_runtime::generic::Era]
+//! - [subxt::utils::AccountId32] instead of [sp_core::crypto::AccountId32]
+//! - [subxt::utils::MultiAddress] instead of [sp_runtime::MultiAddress]
+//! - [subxt::utils::H160], [subxt::utils::H256] and [subxt::utils::H512] instead of [sp_core::H256], [sp_core::H160] and [sp_core::H512]
+//! - [subxt::hash] instead of [sp_runtime::MultiAddress]
+//! - [subxt::config::substrate::Era] instead of [sp_runtime::generic::Era]
+//! - [subxt::config::substrate::SubstrateHeader] instead of [sp_runtime::generic::Header]
+//! - [subxt::config::substrate::AssetTip] instead of [pallet_transaction_payment::ChargeTransactionPayment]
+//! - [subxt::config::substrate::BlakeTwo256] instead of [sp_runtime::generic::Era]
+//! - [subxt::config::substrate] instead of [sp_runtime::generic::Era]
+//! - [subxt::config::substrate::Era] instead of [sp_runtime::generic::Era]

+//!
+//! In this example we connect to a parachain and subscribe to its blocks.
+//! There are many parachains on Polkadot and Kusama. Connecting to a parachain (or any other substrate based blockchain) with subxt requires 2 steps:
+//!
+//! 1. Fetching the chains metadata to generate a static interface via the subxt codegen.
+//! 2. Creating a config struct that implements `subxt::Config` to give some type information
+//! that is currently not covered by the metadata.
+//!
+//! We now show these steps in detail. As an example we use the
+//! ["Ajuna"](https://parachains.info/details/ajuna_network/) parachain that is currently (2023-06-26)
+//! deployed on Polkadot and [Kusama (as "Bajun")](https://parachains.info/details/bajun_network).
+//!
+//!
+//! ## 1. Fetch the Metadata
+//!
+//! To fetch the metadata for the Ajuna network, we need to have the URL of an RPC node.
+//! We can find "Ajuna Network" by looking through the sidebar on [Polkadot.js](https://polkadot.js.org/apps/).
+//! We connect to the node, which leads us to [this page](https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Frpc-parachain.ajuna.network#/explorer).
+//! In the url we can already see the url of the RPC endpoint of the node. It is also printed to the Javascript console of the browser:
+//! `WS endpoint= wss://rpc-parachain.ajuna.network`.
+//!
+//! ```

 //! RPC endpoint of the chain.

-//! # Connecting to a parachain with Subxt
-//!
-//! In this example we connect to a parachain and subscribe to its blocks.
-//! There are many parachains on Polkadot and Kusama. Connecting to a parachain (or any other substrate based blockchain) with subxt requires 2 steps:
-//!
-//! 1. Fetching the chains metadata to generate a static interface via the subxt codegen.
-//! 2. Creating a config struct that implements `subxt::Config` to give some type information
-//! that is currently not covered by the metadata.
-//!
-//! We now show these steps in detail. As an example we use the
-//! ["Ajuna"](https://parachains.info/details/ajuna_network/) parachain that is currently (2023-06-26)
-//! deployed on Polkadot and [Kusama (as "Bajun")](https://parachains.info/details/bajun_network).
-//!
-//!
-//! ## 1. Fetch the Metadata
-//!
-//! To fetch the metadata for the Ajuna network, we need to have the URL of an RPC node.
-//! We can find "Ajuna Network" by looking through the sidebar on [Polkadot.js](https://polkadot.js.org/apps/).
-//! We connect to the node, which leads us to [this page](https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Frpc-parachain.ajuna.network#/explorer).
-//! In the url we can already see the url of the RPC endpoint of the node. It is also printed to the Javascript console of the browser:
-//! `WS endpoint= wss://rpc-parachain.ajuna.network`.
-//!
-//! ```
-//! subxt metadata --url ajuna_metadata.scale
-//! ```
-//!
-//!
-//!
-//! In order to connect to a
-//! chain we first need to fetch its metadata. This requires us to know a valid
-//! RPC endpoint of the chain.
-//! The [Substrate Chains Runtime Api Doc Center](https://substrate.rs/index.html) lists parachains
-//! on Polkadot and Kusama and gives us a list of RPC endpoints for each parachain. Alternatively
-//! we can also look for the RPC endpoint of a chain via [Polkadot.js](https://polkadot.js.org/apps/).
-//! In the side menu, you can select a Polkadot/Kusama parachain. The hit the "Switch" button and
-//! let the page load the chains data. The RPC endpoint url can be found as part of the url.
-//! You can also open the console, to see the RPC endpoint url printed without URL-encoded special characters.
-//!
-//! Let's go through an example for the "Ajuna" parachain on Polkadot.
-//! Selecting it in the [Polkadot.js](https://polkadot.js.org/apps/) menu, then opening the console
-//! lets us observe the following output: `WS endpoint= wss://rpc-parachain.ajuna.network`
-//!
-//! We can now get the metadata of the chain via the subxt-cli tool.
-//! It is important to note that we need to add a `:433` as the port number here:
-//! ```txt
-//! metadata --url wss://rpc-parachain.ajuna.network:443 > artifacts/ajuna_metadata.scale
-//! ```
-//!
-//! This allows us to construct a module with the ajuna types, calls,

+//! In this example we use the _uniques_ pallet of the polakdot asset hub parachain.

+//! There are many parachains on Polkadot and Kusama. Using Subxt to connect to a parachain
 //! (or any other custom, substrate based chain) requires 2 steps:
 //!
 //! 1. Fetching the chains metadata to generate a static interface via the subxt codegen.
 //! 2. Creating a config struct that implements `subxt::Config` to give some type information
 //! that is currently not covered by the metadata.
 //!
-//! We now show these steps in detail for the ["Statemint"](https://parachains.info/details/statemint) parachain, 
-//! also known as "Asset Hub" that is currently (as of 2023-06-26)
-//! deployed on Polkadot and [Kusama (as "Statemine")](https://parachains.info/details/statemine).
+//! This example shows you how to connect to the ["Statemint"](https://parachains.info/details/statemint) parachain,
+//! also known as "Asset Hub", both locally and remotely.

-//! # 1. Fetch the Metadata
+//! ### Example 1: Subscribe to blocks of the official ["Polkadot Asset Hub"](https://parachains.info/details/statemint)
+//!
+//! ```
+//! cargo run --example fetch_blocks.rs
+//! ```
+//!
+//! ### Example 2: Create an NFT on a local parachain
+//!
+//! This requires you to spin up a local asset hub parachain using Zombienet. Please see the instructions in the example.
+//! ```
+//! cargo run --example create_nft.rs
+//! ```
+//!
+//! # How to get the parachains metadata
 //!
 //! To fetch the metadata for the Statemint parachain, we need to have the URL of an RPC node.
 //! We can find the "Asset Hub" entry, by looking through the sidebar on [Polkadot.js](https://polkadot.js.org/apps/).
@@ -19,351 +31,21 @@
 //! In the URL of the page we can already see the URL of the RPC endpoint of the node as a query parameter. It is also printed

-//! Let's create a separate crate for the statically generated interface.
-//! Keeping the metadata and the resulting generated code in a separate crate

-//!
-//! ```txt
-//! cargo new metadata --lib
-//! ```
-//!
-//! In the new crate we can now get the metadata via the [subxt cli](https://crates.io/crates/subxt-cli) tool.
+//! We can now get the metadata via the [subxt cli](https://crates.io/crates/subxt-cli) tool.
 //! It is important to specify the port as `:443` like so:
 //! ```txt
 //! subxt metadata  --url wss://polkadot-asset-hub-rpc.polkadot.io:443 > statemint_metadata.scale
 //! ```
-//! The metadata is saved as `statemint_metadata.scale`. We need to add subxt as a dependency with `cargo add subxt`
-//! and then we can replace the code in lib.rs with the following:
+//! The metadata is saved as `statemint_metadata.scale` and can be used to create the statically generated interface for the parachain:
 //! ```
 //! #[subxt::subxt(runtime_metadata_path = "statemint_metadata.scale")]
 //! pub mod statemint {}
 //! ```
-//! We use the `metadata` crate as a dependency in our main project and have access to
-//! all the pallets and calls of Ajuna via the exported module `metadata::statemint`.
-//!
-//! # 2. Create the Config
-//!
-//! To construct a config, we need to investigate which types Statemint uses as `AccountId`, `Hasher`, etc.
-//! We need to take a look at the source code of Statemint and find out how it implements some substrate functionalities.
-//! Statemint (Polkadot Asset Hub) is part of the [Cumulus Github repository](https://github.com/paritytech/cumulus).
-//! The crate defining the parachains runtime can be found [here](https://github.com/paritytech/cumulus/tree/master/parachains/runtimes/assets/asset-hub-polkadot).
-//!
-//! ## 2.1 Create the config from scratch
-//!
-//! First we want to create the config from scratch to understand all the details.
-//!
-//! ### AccountId, Index, Hash, Hasher and Header
-//! We need to check, where the parachains runtime implements the frame_system::Config trait.
-//! Look for a code fragment like `impl frame_system::Config for Runtime { ... }` In the source code.
-//! For Statemint we find it [here](https://github.com/paritytech/cumulus/tree/master/parachains/runtimes/assets/asset-hub-polkadot/src/lib.rs#L179).
-//! The `AccountId`, `Index`, `Hash` and `Header` types of the [frame_system::Config] should also be the ones
-//! we want to use for implementing [subxt::Config].
-//! In the Case of Statemint (Asset Hub) they are:
-//!
-//! - AccountId: [sp_core::crypto::AccountId32]
-//! - Index: [u32]
-//! - Hash: [sp_core::H256]
-//! - Hasher (type `Hashing` in [frame_system::Config]): [sp_runtime::traits::BlakeTwo256]
-//! - Header: [sp_runtime::generic::Header<u32, sp_runtime::traits::BlakeTwo256>](sp_runtime::generic::Header)
-//!
-//! ### Address, Signature, ExtrinsicParams
-//! A Substrate runtime is typically constructed by using the [frame_support::construct_runtime] macro.
-//! In this macro, we need to specify the type of an `UncheckedExtrinsic`. Most of the time, the `UncheckedExtrinsic` will be of the type
-//! [sp_runtime::generic::UncheckedExtrinsic<Address, RuntimeCall, Signature, SignedExtra>](sp_runtime::generic::UncheckedExtrinsic).
-//! The generic parameters `Address` and `Signature` specified when declaring the `UncheckedExtrinsic` type
-//! are the types for `Address` and `Signature` we should use when implementing the [subxt::Config] trait.
-//! In case of Statemint (Polkadot Asset Hub) we see the following types being used in `UncheckedExtrinsic`:
-//!
-//! - Address: [sp_runtime::MultiAddress<Self::AccountId, ()>](sp_runtime::MultiAddress)
-//! - Signature: [sp_runtime::MultiSignature]
-//!
-//! #### ExtrinsicParams
-//! The `ExtrinsicParams` type is the most complicated to set up, but it can be derived from
-//! the `SignedExtra` parameter of the `UncheckedExtrinsic` of your parachain. The `SignedExtra` parameter is a tuple in most cases,
-//! where each field of the tuple corresponds to 0-1 fields in the `ExtrinsicParams` struct we want to create.
-//! It looks like [this](https://github.com/paritytech/cumulus/tree/master/parachains/runtimes/assets/asset-hub-polkadot/src/lib.rs#L779) for the Statemint parachain:
-//!
-//! ```rs
-//! pub type SignedExtra = (
-//!     frame_system::CheckNonZeroSender<Runtime>,
-//!     frame_system::CheckSpecVersion<Runtime>,
-//!     frame_system::CheckTxVersion<Runtime>,
-//!     frame_system::CheckGenesis<Runtime>,
-//!     frame_system::CheckEra<Runtime>,
-//!     frame_system::CheckNonce<Runtime>,
-//!     frame_system::CheckWeight<Runtime>,
-//!     pallet_asset_tx_payment::ChargeAssetTxPayment<Runtime>,
-//! );
-//! ```
-//!
-//! The `ExtrinsicParams` struct is basically a collection of fields that can be grouped into two categories:
-//! _extra parameters_ and _additional parameters_. _Extra parameters_ are taken into account when
-//! signing a transaction and sent along with it, while _additional parameters_ are only used during
-//! the signing step but _not_ sent along with the transaction.
-//!
-//! Each element of the `SignedExtra` tuple implements [parity_scale_codec::codec::Encode] and [sp_runtime::traits::SignedExtension]
-//! which has an associated type `AdditionalSigned` that also implements [parity_scale_codec::codec::Encode]. Let's look at the underlying types for each tuple element.
-//! All zero-sized types have been replaced by `()` for simplicity.
-//!
-//! | tuple element                        | struct type                                     | `AdditionalSigned` type          |
-//! | ------------------------------------ | ----------------------------------------------- | ---------------------------------|
-//! | [frame_system::CheckNonZeroSender]   | ()                                              | ()                               |
-//! | [frame_system::CheckSpecVersion]     | ()                                              | [u32]                            |
-//! | [frame_system::CheckTxVersion]       | ()                                              | [u32]                            |
-//! | [frame_system::CheckGenesis]         | ()                                              | `Config::Hash` = [sp_core::H256] |
-//! | [frame_system::CheckMortality]       | [sp_runtime::generic::Era]                      | `Config::Hash` = [sp_core::H256] |
-//! | [frame_system::CheckNonce]           | [Config::Index] = [u32]                         | ()                               |
-//! | [frame_system::CheckWeight]          | ()                                              | ()                               |
-//! | [frame_system::ChargeAssetTxPayment] | [pallet_asset_tx_payment::ChargeAssetTxPayment] | ()                               |
-//!
-//! All types in the `struct type` column make up our _extra parameters_.
-//! We can put them together into a struct, ignoring all zero-sized types.
-//! The types of the last column make up our _additional parameters_. Here
-//! we can also ignore the zero-sized types. We can name the fields however we like,
-//! however their order in the struct should match the order in the `SignedExtra` tuple (see table).
-//! Beware that some numbers might be compact encoded, when encoding the struct, some might not be.
-//! Please check the exact struct type definition here. For example the definition for CheckNonce is
-//! `CheckNonce<T: Config>(#[codec(compact)] pub T::Index)`. We can see that the `#[codec(compact)`
-//! attribute tells us that the `u32` value needs to be compact encoded.
-//!
-//! Because the `pallet_asset_tx_payment::ChargeAssetTxPayment<Runtime>` struct requires us to pass the
-//! struct of our `Runtime` as a generic argument, we decide to just recreate the struct here. This prohibits us
-//! from pulling in tons of unneeded dependencies. This is a pattern that you might see often,
-//! especially because substrate crates and their types are quite big, clunky and entangled sometimes.
-//!
-//! With all these types collected, we can create two structs: `StatemintExtraParams` and `StatemintAdditionalParams`.
-//! Then we combine them into a `StatemintExtrinsicParams` struct for which we implement the [subxt::config::ExtrinsicParams] trait, see below.
-//! Now we have all the parts we need to create our config `StatemintConfig` and implment the [subxt::Config] trait on it.
-//! Note that StatemintConfig is an empty enum, an _uninhabited type_ that is never means to be instantiated
-//! but just gives type information to various interfaces of _subxt_.
-//!
-//! ## 2.2 Simplifying the config
-//!
-//! Now you should be able to create a config for a parachain from scratch and understand the details of its construction.
-//! However this is quite a tedious process, so subxt provides some sane defaults that can make your life easier.
-//! First, let's ditch the dependencies to [sp_core] and [sp_runtime].
-//! We should not be forced to utilize these traits whenever we create a config for a chain.
-//! That is why subxt provides some types that can function as drop in replacements for some types in [sp_core] and [sp_runtime].
-//! You can use:
-//! - [subxt::config::extrinsic_params::Era] instead of [sp_runtime::generic::Era]
-//! - [subxt::utils::AccountId32] instead of [sp_core::crypto::AccountId32]
-//! - [subxt::utils::MultiAddress] instead of [sp_runtime::MultiAddress]
-//! - [subxt::utils::H160], [subxt::utils::H256] and [subxt::utils::H512] instead of [sp_core::H256], [sp_core::H160] and [sp_core::H512]
-//! - [subxt::hash] instead of [sp_runtime::MultiAddress]
-//! - [subxt::config::substrate::Era] instead of [sp_runtime::generic::Era]
-//! - [subxt::config::substrate::SubstrateHeader] instead of [sp_runtime::generic::Header]
-//! - [subxt::config::substrate::AssetTip] and [subxt::config::polkadot::PlainTip] instead of [pallet_transaction_payment::ChargeTransactionPayment]
-//! - [subxt::config::substrate::BlakeTwo256] instead of [sp_core::Blake2Hasher] or [sp_runtime::traits::BlakeTwo256]
-//! - [subxt::config::substrate::DigestItem] and [subxt::config::substrate::Digest] instead of types from [sp_runtime::generic::digest]
-//! - [subxt::config::substrate::ConsensusEngineId] instead of [sp_runtime::ConsensusEngineId]
-//!
-//! With these optimizations, our config can look like the `StatemintConfigWithSubxtTypes` below.
 //!
-//! ## 2.3. Use the Substrate default config as much as possible
-//!
-//! Because most substrate based chains share a great deal of types, _subxt_ already provides two configs:
-//! - [subxt::SubstrateConfig] configured for the default [substrate node template](https://github.com/substrate-developer-hub/substrate-node-template)
-//! - [subxt::PolkadotConfig] configured for the [polkadot node implementation](https://github.com/paritytech/polkadot)
-//!
-//! Even those two just differ in the type of the `Tip` and `MultiAddress`.
-//! Statemint (Polkadot Asset Hub) seems to match the Polkadot config in almost all points, except for the `ExtrinsicParams`.
-//! Here the tips follow the same structure as for the default substrate node.
-//! We can now simply build the config for Statemint from the building blocks provided
-//! by [subxt::SubstrateConfig] and [subxt::PolkadotConfig] as shown below in `StatemintConfigComposed`.
-//!
-//! All configs we constructed, `StatemintConfig`, `StatemintConfigWithSubxtTypes` and `StatemintConfigComposed` should behave in the same way.
-//! All three ways are valid for constructing a config. Choose one depending on your use case.
-//!
-//! # 3. Try the examples
-//! 
-//! We have two examples of interacting with the parachain, that you can try. 
-//! You find them in the bin directory of this crate. Please check them out.

+//! # Creating a Config
+//!
+//! Subxt requires you to provide a type implementing [`crate::config::Config`] in order to connect to a node.
+//! The [`crate::config::Config`] trait for the most part mimics the `frame_system::Config` trait.
+//! For most use cases, you can just use one of the following Configs shipped with Subxt:
+//!
+//! - [`PolkadotConfig`](crate::config::PolkadotConfig) for talking to Polkadot nodes, and
+//! - [`SubstrateConfig`](crate::config::SubstrateConfig) for talking to generic nodes built with Substrate.
+//!
+//! # How to create a Config for a custom chain?
+//!
+//! We now show in depth how a subxt Config can be created for a parachain, using the ["Statemint"](https://parachains.info/details/statemint) parachain,
+//! also known as "Asset Hub" as an example. It is currently (as of 2023-06-26)
+//! deployed on Polkadot and [Kusama (as "Statemine")](https://parachains.info/details/statemine).
+//! We also provide a separate example on [how to interact with the parachain](https://github.com/paritytech/subxt/tree/master/examples/parachain-example).
+//!
+//! To construct a config, we need to investigate which types Statemint uses as `AccountId`, `Hasher`, etc.
+//! We need to take a look at the source code of Statemint and find out how it implements some substrate functionalities.
+//! Statemint (Polkadot Asset Hub) is part of the [Cumulus Github repository](https://github.com/paritytech/cumulus).
+//! The crate defining the parachains runtime can be found [here](https://github.com/paritytech/cumulus/tree/master/parachains/runtimes/assets/asset-hub-polkadot).
+//!
+//! ## 1. Create the config from scratch
+//!
+//! First we want to create the config from scratch to understand all the details.
+//!
+//! ### AccountId, Index, Hash, Hasher and Header
+//! We need to check, where the parachains runtime implements the frame_system::Config trait.
+//! Look for a code fragment like `impl frame_system::Config for Runtime { ... }` In the source code.
+//! For Statemint we find it [here](https://github.com/paritytech/cumulus/tree/master/parachains/runtimes/assets/asset-hub-polkadot/src/lib.rs#L179).
+//! The `AccountId`, `Index`, `Hash` and `Header` types of the [frame_system::Config] should also be the ones
+//! we want to use for implementing [subxt::Config].
+//! In the Case of Statemint (Asset Hub) they are:
+//!
+//! - AccountId: [sp_core::crypto::AccountId32]
+//! - Index: [u32]
+//! - Hash: [sp_core::H256]
+//! - Hasher (type `Hashing` in [frame_system::Config]): [sp_runtime::traits::BlakeTwo256]
+//! - Header: [sp_runtime::generic::Header<u32, sp_runtime::traits::BlakeTwo256>](sp_runtime::generic::Header)
+//!
+//! ### Address, Signature, ExtrinsicParams
+//! A Substrate runtime is typically constructed by using the [frame_support::construct_runtime] macro.
+//! In this macro, we need to specify the type of an `UncheckedExtrinsic`. Most of the time, the `UncheckedExtrinsic` will be of the type
+//! [sp_runtime::generic::UncheckedExtrinsic<Address, RuntimeCall, Signature, SignedExtra>](sp_runtime::generic::UncheckedExtrinsic).
+//! The generic parameters `Address` and `Signature` specified when declaring the `UncheckedExtrinsic` type
+//! are the types for `Address` and `Signature` we should use when implementing the [subxt::Config] trait.
+//! In case of Statemint (Polkadot Asset Hub) we see the following types being used in `UncheckedExtrinsic`:
+//!
+//! - Address: [sp_runtime::MultiAddress<Self::AccountId, ()>](sp_runtime::MultiAddress)
+//! - Signature: [sp_runtime::MultiSignature]
+//!
+//! #### ExtrinsicParams
+//! The `ExtrinsicParams` type is the most complicated to set up, but it can be derived from
+//! the `SignedExtra` parameter of the `UncheckedExtrinsic` of your parachain. The `SignedExtra` parameter is a tuple in most cases,
+//! where each field of the tuple corresponds to 0-1 fields in the `ExtrinsicParams` struct we want to create.
+//! It looks like [this](https://github.com/paritytech/cumulus/tree/master/parachains/runtimes/assets/asset-hub-polkadot/src/lib.rs#L779) for the Statemint parachain:
+//!
+//! ```rs
+//! pub type SignedExtra = (
+//!     frame_system::CheckNonZeroSender<Runtime>,
+//!     frame_system::CheckSpecVersion<Runtime>,
+//!     frame_system::CheckTxVersion<Runtime>,
+//!     frame_system::CheckGenesis<Runtime>,
+//!     frame_system::CheckEra<Runtime>,
+//!     frame_system::CheckNonce<Runtime>,
+//!     frame_system::CheckWeight<Runtime>,
+//!     pallet_asset_tx_payment::ChargeAssetTxPayment<Runtime>,
+//! );
+//! ```
+//!
+//! The `ExtrinsicParams` struct is basically a collection of fields that can be grouped into two categories:
+//! _extra parameters_ and _additional parameters_. _Extra parameters_ are taken into account when
+//! signing a transaction and sent along with it, while _additional parameters_ are only used during
+//! the signing step but _not_ sent along with the transaction.
+//!
+//! Each element of the `SignedExtra` tuple implements [parity_scale_codec::codec::Encode] and [sp_runtime::traits::SignedExtension]
+//! which has an associated type `AdditionalSigned` that also implements [parity_scale_codec::codec::Encode]. Let's look at the underlying types for each tuple element.
+//! All zero-sized types have been replaced by `()` for simplicity.
+//!
+//! | tuple element                        | struct type                                     | `AdditionalSigned` type          |
+//! | ------------------------------------ | ----------------------------------------------- | ---------------------------------|
+//! | [frame_system::CheckNonZeroSender]   | ()                                              | ()                               |
+//! | [frame_system::CheckSpecVersion]     | ()                                              | [u32]                            |
+//! | [frame_system::CheckTxVersion]       | ()                                              | [u32]                            |
+//! | [frame_system::CheckGenesis]         | ()                                              | `Config::Hash` = [sp_core::H256] |
+//! | [frame_system::CheckMortality]       | [sp_runtime::generic::Era]                      | `Config::Hash` = [sp_core::H256] |
+//! | [frame_system::CheckNonce]           | [Config::Index] = [u32]                         | ()                               |
+//! | [frame_system::CheckWeight]          | ()                                              | ()                               |
+//! | [frame_system::ChargeAssetTxPayment] | [pallet_asset_tx_payment::ChargeAssetTxPayment] | ()                               |
+//!
+//! All types in the `struct type` column make up our _extra parameters_.
+//! We can put them together into a struct, ignoring all zero-sized types.
+//! The types of the last column make up our _additional parameters_. Here
+//! we can also ignore the zero-sized types. We can name the fields however we like,
+//! however their order in the struct should match the order in the `SignedExtra` tuple (see table).
+//! Beware that some numbers might be compact encoded, when encoding the struct, some might not be.
+//! Please check the exact struct type definition here. For example the definition for CheckNonce is
+//! `CheckNonce<T: Config>(#[codec(compact)] pub T::Index)`. We can see that the `#[codec(compact)`
+//! attribute tells us that the `u32` value needs to be compact encoded.
+//!
+//! Because the `pallet_asset_tx_payment::ChargeAssetTxPayment<Runtime>` struct requires us to pass the
+//! struct of our `Runtime` as a generic argument, we decide to just recreate the struct here. This prohibits us
+//! from pulling in tons of unneeded dependencies. This is a pattern that you might see often,
+//! especially because substrate crates and their types are quite big, clunky and entangled sometimes.
+//!
+//! With all these types collected, we can create two structs: `StatemintExtraParams` and `StatemintAdditionalParams`.
+//! Then we combine them into a `StatemintExtrinsicParams` struct for which we implement the [subxt::config::ExtrinsicParams] trait, see below.
+//! Now we have all the parts we need to create our config `StatemintConfig` and implment the [subxt::Config] trait on it.
+//! Note that StatemintConfig is an empty enum, an _uninhabited type_ that is never means to be instantiated
+//! but just gives type information to various interfaces of _subxt_.
+//!
+//! ```rust,ignore
+#![doc = include_str ! ("../../../../examples/parachain-example/src/statemint_config_verbose.rs")]
+//! ```
+//!
+//! ## 2. Simplifying the config
+//!
+//! Now you should be able to create a config for a parachain from scratch and understand the details of its construction.
+//! However this is quite a tedious process, so subxt provides some sane defaults that can make your life easier.
+//! First, let's ditch the dependencies to [sp_core] and [sp_runtime].
+//! We should not be forced to utilize these traits whenever we create a config for a chain.
+//! That is why subxt provides some types that can function as drop in replacements for some types in [sp_core] and [sp_runtime].
+//! You can use:
+//! - [crate::config::extrinsic_params::Era] instead of [sp_runtime::generic::Era]
+//! - [crate::utils::AccountId32] instead of [sp_core::crypto::AccountId32]
+//! - [crate::utils::MultiAddress] instead of [sp_runtime::MultiAddress]
+//! - [crate::utils::H160], [crate::utils::H256] and [crate::utils::H512] instead of [sp_core::H256], [sp_core::H160] and [sp_core::H512]
+//! - [crate::utils::MultiAddress] instead of [sp_runtime::MultiAddress]
+//! - [crate::config::substrate::Era] instead of [sp_runtime::generic::Era]
+//! - [crate::config::substrate::SubstrateHeader] instead of [sp_runtime::generic::Header]
+//! - [crate::config::substrate::AssetTip] and [crate::config::polkadot::PlainTip] instead of [pallet_transaction_payment::ChargeTransactionPayment](https://docs.rs/pallet-transaction-payment/latest/pallet_transaction_payment/struct.ChargeTransactionPayment.html)
+//! - [crate::config::substrate::BlakeTwo256] instead of [sp_core::Blake2Hasher] or [sp_runtime::traits::BlakeTwo256]
+//! - [crate::config::substrate::DigestItem] and [crate::config::substrate::Digest] instead of types from [sp_runtime::generic::digest]
+//! - [crate::config::substrate::ConsensusEngineId] instead of [sp_runtime::ConsensusEngineId]
+//!
+//! With these optimizations, our config can look like this:
+//!
+//! ```rust,ignore
+#![doc = include_str ! ("../../../../examples/parachain-example/src/statemint_config_with_subxt_types.rs")]
+//! ```
+//!
+//! ## 3. Use the [`PolkadotConfig`](crate::PolkadotConfig) and [`SubstrateConfig`](crate::SubstrateConfig) to compose a Config
+//!
+//! Because most substrate based chains share a great deal of types, _subxt_ already provides two configs:
+//! - [`SubstrateConfig`](crate::SubstrateConfig) configured for the default [substrate node template](https://github.com/substrate-developer-hub/substrate-node-template)
+//! - [`PolkadotConfig`](crate::PolkadotConfig) configured for the [polkadot node implementation](https://github.com/paritytech/polkadot)
+//!
+//! Even those two just differ in the type of the `Tip` and `MultiAddress`.
+//! Statemint (Polkadot Asset Hub) seems to match the Polkadot config in almost all points, except for the `ExtrinsicParams`.
+//! Here the tips follow the same structure as for the default substrate node.
+//! We can now simply build the config for Statemint from the building blocks provided
+//! by [subxt::SubstrateConfig] and [subxt::PolkadotConfig] as shown below.
+//!
+//!
+//! ```rust,ignore
+#![doc = include_str ! ("../../../../examples/parachain-example/src/statemint_config_composed.rs")]
+//! ```

+# parachain-example
+
+This example showcases working with Subxt and Zombienet to try out connecting to a locally deployed parachain, here
+["Statemint"](https://parachains.info/details/statemint), also known as "Asset Hub".
+
+## Running the example
+
+### 1. Install `zombienet`
+
+[Zombienet](https://github.com/paritytech/zombienet) is a tool for quickly spinning up a (local) blockchain
+network. We will use it to start up a local Asset Hub for us.
+
+Please follow the install guide in the [zombienet github repo](https://github.com/paritytech/zombienet) to
+install it.
+
+### 2. `polkadot`
+
+We need a relay chain. Build the polkadot binary from the [polkadot github repo](https://github.com/paritytech/polkadot)
+and install it in your path:
+
+```txt
+git clone https://github.com/paritytech/polkadot.git
+cd polkadot
+cargo build --release
+cargo install --path .
+```
+
+### 3. `polkadot-parachain`
+
+The Asset Hub is part of the [cumulus github repo](https://github.com/paritytech/cumulus), an SDK for developing
+parachains. Building the cumulus workspace produces a binary called `polkadot-parachain` which can be used to run
+Asset Hub nodes.
+
+```txt
+git clone https://github.com/paritytech/cumulus.git
+cd cumulus
+cargo build --release
+cargo install --path .
+```
+
+### 4. Run the parachain locally
+
+With these binaries installed, Zombienet can now get the parachain running locally from a configuration file, `asset-hub-zombienet.toml`
+in this case. We need to have at least 2 validator nodes running via the `polkadot` binary, and an Asset Hub node running via the
+`polkadot-parachain` binary. Zombienet starts these up, and gets the parachain registered with the validator nodes for us. To do that,
+run:
+
+```txt
+zombienet -p native spawn asset-hub-zombienet.toml
+```
+
+Zombienet uses Kubernetes by default, but we can use it without Kubernetes by providing the `-p native` flag.
+
+You might have noticed that we use `chain = "rococo-local"` in the `asset-hub-zombienet.toml` file for the relay chain. This is just to
+make the epoch time shorter and should have no effect on your interactions with the parachain. Polkadot / Kusama / Rococo have different
+epoch times of `24h` / `2h` / `2min` respectively.
+
+### 5. Run the example
+
+The parachain is only registered after the first epoch. So after the previous step, we need to wait 2 minutes until the parachain becomes
+interactive and produces blocks. At this point, we can run:
+
+```
+cargo run --bin
+```
+
+To run our example code.
+
+## Dev notes
+
+We can obtain the metadata for Statemint via the [subxt cli](https://crates.io/crates/subxt-cli) tool, like so:
+
+```txt
+subxt metadata  --url wss://polkadot-asset-hub-rpc.polkadot.io:443 > statemint_metadata.scale
+```
+
+It is important to explicitly specify the port as `443`.
+
+One way to find a suitable URL to obtain this from is by looking through the sidebar on [Polkadot.js](https://polkadot.js.org/apps/)
+to find the Asset Hub entry, and seeing which RPC node URLs it uses.

-//! # Tutorial: Subxt setup to interact with custom chains
-//!
-//! There are many parachains on Polkadot and Kusama. Using Subxt to connect to a parachain
-//! (or any other custom, substrate based chain) requires 2 steps:
-//!
-//! 1. Fetching the chains metadata to generate a static interface via the subxt codegen.
-//! 2. Creating a config struct that implements `subxt::Config` to give some type information
-//! that is currently not covered by the metadata.
-//!
-//! This example shows you how to connect to the ["Statemint"](https://parachains.info/details/statemint) parachain,
-//! also known as "Asset Hub", both locally and remotely.
-//!
-//! ### Example 1: Subscribe to blocks of the official ["Polkadot Asset Hub"](https://parachains.info/details/statemint)
-//!
-//! ```
-//! cargo run --example fetch_blocks.rs
-//! ```
-//!
-//! ### Example 2: Create an NFT on a local parachain
-//!
-//! This requires you to spin up a local asset hub parachain using Zombienet. Please see the instructions in the example.
-//! ```
-//! cargo run --example create_nft.rs
-//! ```
-//!
-//! # How to get the parachains metadata
-//!
-//! To fetch the metadata for the Statemint parachain, we need to have the URL of an RPC node.
-//! We can find the "Asset Hub" entry, by looking through the sidebar on [Polkadot.js](https://polkadot.js.org/apps/).
-//! We connect to the node ("via Parity"), which leads us to [this page](https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Fpolkadot-asset-hub-rpc.polkadot.io#/explorer).
-//! In the URL of the page we can already see the URL of the RPC endpoint of the node as a query parameter. It is also printed
-//! to the Javascript console of the browser: `WS endpoint= wss://polkadot-asset-hub-rpc.polkadot.io`.
-//!
-//! We can now get the metadata via the [subxt cli](https://crates.io/crates/subxt-cli) tool.
-//! It is important to specify the port as `:443` like so:
-//! ```txt
-//! subxt metadata  --url wss://polkadot-asset-hub-rpc.polkadot.io:443 > statemint_metadata.scale
-//! ```
-//! The metadata is saved as `statemint_metadata.scale` and can be used to create the statically generated interface for the parachain:
-//! ```
-//! #[subxt::subxt(runtime_metadata_path = "statemint_metadata.scale")]
-//! pub mod statemint {}
-//! ```
-//!

+
+To run the app locally we first install Trunk, a WASM bundler:
+
+```
+cargo install --locked trunk
+```
+
+You need to have a local polkadot/substrate node with it's JSON-RPC HTTP server running at 127.0.0.1:9933 in order for the examples to be working.
+If you have a `polkadot` binary already, running this should be sufficient:
+
+```
+polkadot --dev
+```
+
+Then, in another terminal, run the app locally with:
+
+```
+trunk serve --open

-//! We now show in depth how a subxt Config can be created for a parachain, using the ["Statemint"](https://parachains.info/details/statemint) parachain,
-//! also known as "Asset Hub" as an example. It is currently (as of 2023-06-26)
-//! deployed on Polkadot and [Kusama (as "Statemine")](https://parachains.info/details/statemine).
-//! We also provide a separate example on [how to interact with the parachain](https://github.com/paritytech/subxt/tree/master/examples/parachain-example).
+//! Some chains may use config that is not compatible with our [`PolkadotConfig`](crate::config::PolkadotConfig) or
+//! [`SubstrateConfig`](crate::config::SubstrateConfig).
+//!
+//! We now walk through how a subxt [`crate::config::Config`] can be created for a parachain, using the

+//! is currently (as of 2023-06-26) deployed on Polkadot and [Kusama (as "Statemine")](https://parachains.info/details/statemine).

 //! To construct a config, we need to investigate which types Statemint uses as `AccountId`, `Hasher`, etc.
 //! We need to take a look at the source code of Statemint and find out how it implements some substrate functionalities.
 //! Statemint (Polkadot Asset Hub) is part of the [Cumulus Github repository](https://github.com/paritytech/cumulus).

+//! Creating the config from scratch is the most arduous approach but also the most flexible, so first we'll walk through
+//! how to do this, and then we'll show how to simplify the process, which can be achieved in most cases.
 //!
 //! ### AccountId, Index, Hash, Hasher and Header
-//! We need to check, where the parachains runtime implements the frame_system::Config trait.
+//!
+//! For these config types, we need to find out where the parachain runtime implements the `frame_system::Config` trait.

+//! - [`sp_core::H256`] is a re-export which subxt also provides as [`crate::config::substrate::H256`].
+//! - [`sp_runtime::traits::BlakeTwo256`] can be swapped with [`crate::config::substrate::BlakeTwo256`].
+//! - [`sp_runtime::generic::Header`] can be swapped with [`crate::config::substrate::SubstrateHeader`].

-//! #### ExtrinsicParams
-//! The `ExtrinsicParams` type is the most complicated to set up, but it can be derived from
-//! the `SignedExtra` parameter of the `UncheckedExtrinsic` of your parachain. The `SignedExtra` parameter is a tuple in most cases,
-//! where each field of the tuple corresponds to 0-1 fields in the `ExtrinsicParams` struct we want to create.
-//! It looks like [this](https://github.com/paritytech/cumulus/tree/master/parachains/runtimes/assets/asset-hub-polkadot/src/lib.rs#L779) for the Statemint parachain:
+//! As above, Subxt has its own versions of these types that can be used instead to avoid pulling in Substrate dependencies.
+//! Using the Subxt versions also makes interacting with generated code (which uses them in some places) a little nicer:
+//!
+//! - [`sp_runtime::MultiAddress`] can be swapped with [`crate::utils::MultiAddress`].
+//! - [`sp_runtime::MultiSignature`] can be swapped with [`crate::utils::MultiSignature`].
+//!
+//! ### ExtrinsicParams
+//!
+//! Parachains each have a set of "signed extensions" configured. Signed extensions provide a means to extend how transactions
+//! work. Each signed extension can potentially encode some "extra" data which is sent along with a transaction, as well as some
+//! "additional" data which is included in the transaction signer payload, but not transmitted along with the transaction.
+//!
+//! The `ExtrinsicParams` config type expects to be given an implementation of the [`crate::config::ExtrinsicParams`] trait.
+//! Implementations of the [`crate::config::ExtrinsicParams`] trait are handed some parameters from Subxt itself, and can
+//! accept arbitrary `OtherParams` from users, and are then expected to provide this "extra" and "additional" data when asked.
+//!
+//! In order to construct a valid implementation of the `ExtrinsicParams` trait, you must first find out which signed extensions
+//! are in use by a chain. This information can be obtained from the `SignedExtra` parameter of the `UncheckedExtrinsic` of your
+//! parachain, which will be a tuple of signed extensions. It can also be obtained from the metadata (see
+//! [`frame_metadata::v15::SignedExtensionMetadata`]).
+//!
+//! For statemint, the signed extensions look like
+//! [this](https://github.com/paritytech/cumulus/tree/master/parachains/runtimes/assets/asset-hub-polkadot/src/lib.rs#L779):
 //!

 //! pub type SignedExtra = (

-//! The `ExtrinsicParams` struct is basically a collection of fields that can be grouped into two categories:
-//! _extra parameters_ and _additional parameters_. _Extra parameters_ are taken into account when
-//! signing a transaction and sent along with it, while _additional parameters_ are only used during
-//! the signing step but _not_ sent along with the transaction.
-//!
 //! Each element of the `SignedExtra` tuple implements [codec::Encode] and [sp_runtime::traits::SignedExtension]

-//! All types in the `struct type` column make up our _extra parameters_.
-//! We can put them together into a struct, ignoring all zero-sized types.
-//! The types of the last column make up our _additional parameters_. Here
-//! we can also ignore the zero-sized types. We can name the fields however we like,
-//! however their order in the struct should match the order in the `SignedExtra` tuple (see table).
-//! Beware that some numbers might be compact encoded, when encoding the struct, some might not be.
-//! Please check the exact struct type definition here. For example the definition for CheckNonce is
-//! `CheckNonce<T: Config>(#[codec(compact)] pub T::Index)`. We can see that the `#[codec(compact)`
-//! attribute tells us that the `u32` value needs to be compact encoded.
-//!
-//! Because the `pallet_asset_tx_payment::ChargeAssetTxPayment<Runtime>` struct requires us to pass the
-//! struct of our `Runtime` as a generic argument, we decide to just recreate the struct here. This prohibits us
-//! from pulling in tons of unneeded dependencies. This is a pattern that you might see often,
-//! especially because substrate crates and their types are quite big, clunky and entangled sometimes.
-//!
-//! With all these types collected, we can create two structs: `StatemintExtraParams` and `StatemintAdditionalParams`.
-//! Then we combine them into a `StatemintExtrinsicParams` struct for which we implement the [crate::config::ExtrinsicParams] trait, see below.
-//! Now we have all the parts we need to create our config `StatemintConfig` and implment the [crate::Config] trait on it.
-//! Note that StatemintConfig is an empty enum, an _uninhabited type_ that is never means to be instantiated
-//! but just gives type information to various interfaces of _subxt_.
+//! which has an associated type `AdditionalSigned` that also implements [codec::Encode]. Let's look at the underlying types

+//! All types in the `struct type` column make up the "extra" data that we're expected to provide. All types in the
+//! `AdditionalSigned` column make up the "additional" data that we're expected to provide. The goal of an
+//! [`crate::config::ExtrinsicParams`] then is to provide the appropriate data for these via [`crate::config::ExtrinsicParams::encode_extra_to()`]
+//! and [`crate::config::ExtrinsicParams::encode_additional_to()`] respectively. If it needs additional parameters from
+//! the user to provide this data, it can obtain it via [`crate::config::ExtrinsicParams::OtherParams`].
+//!
+//! Given the above information, here is a fairly naive approach to implementing config for Statemint, including the
+//! [`crate::config::ExtrinsicParams`] trait, in a compatible way:
 //!
 //! ```rust,ignore
-#![doc = include_str ! ("../../../../examples/parachain-example/src/statemint_config_verbose.rs")]
+#![doc = include_str ! ("../../../examples/setup_config_custom.rs")]
 //! ```
 //!
-//! ## 2. Simplifying the config
-//!
-//! Now you should be able to create a config for a parachain from scratch and understand the details of its construction.
-//! However this is quite a tedious process, so subxt provides some sane defaults that can make your life easier.
-//! First, let's ditch the dependencies to [sp_core] and [sp_runtime].
-//! We should not be forced to utilize these traits whenever we create a config for a chain.
-//! That is why subxt provides some types that can function as drop in replacements for some types in [sp_core] and [sp_runtime].
-//! You can use:
-//! - [crate::config::extrinsic_params::Era] instead of [sp_runtime::generic::Era]
-//! - [crate::utils::AccountId32] instead of [sp_core::crypto::AccountId32]
-//! - [crate::utils::MultiAddress] instead of [sp_runtime::MultiAddress]
-//! - [crate::utils::H160], [crate::utils::H256] and [crate::utils::H512] instead of [sp_core::H256], [sp_core::H160] and [sp_core::H512]
-//! - [crate::utils::MultiAddress] instead of [sp_runtime::MultiAddress]
-//! - [crate::config::substrate::Era] instead of [sp_runtime::generic::Era]
-//! - [crate::config::substrate::SubstrateHeader] instead of [sp_runtime::generic::Header]
-//! - [crate::config::substrate::AssetTip] and [crate::config::polkadot::PlainTip] instead of [pallet_transaction_payment::ChargeTransactionPayment](https://docs.rs/pallet-transaction-payment/latest/pallet_transaction_payment/struct.ChargeTransactionPayment.html)
-//! - [crate::config::substrate::BlakeTwo256] instead of [sp_core::Blake2Hasher] or [sp_runtime::traits::BlakeTwo256]
-//! - [crate::config::substrate::DigestItem] and [crate::config::substrate::Digest] instead of [sp_runtime::generic::Digest] and [sp_runtime::generic::DigestItem]
-//! - [crate::config::substrate::ConsensusEngineId] instead of [sp_runtime::ConsensusEngineId]
-//!
-//! With these optimizations, our config can look like this:
-//!
-//! ```rust,ignore
-#![doc = include_str ! ("../../../../examples/parachain-example/src/statemint_config_with_subxt_types.rs")]
-//! ```
-//!
-//! ## 3. Use the [`PolkadotConfig`](crate::PolkadotConfig) and [`SubstrateConfig`](crate::SubstrateConfig) to compose a Config
+//! ## Using [`PolkadotConfig`](crate::PolkadotConfig) and [`SubstrateConfig`](crate::SubstrateConfig) values to compose a Config
 //!
 //! Because most substrate based chains share a great deal of types, _subxt_ already provides two configs:
-//! - [`SubstrateConfig`](crate::SubstrateConfig) configured for the default [substrate node template](https://github.com/substrate-developer-hub/substrate-node-template)
-//! - [`PolkadotConfig`](crate::PolkadotConfig) configured for the [polkadot node implementation](https://github.com/paritytech/polkadot)
+//! - [`SubstrateConfig`](crate::SubstrateConfig) configured for the default
+//!   [substrate node template](https://github.com/substrate-developer-hub/substrate-node-template)
+//! - [`PolkadotConfig`](crate::PolkadotConfig) configured for the
+//!   [polkadot node implementation](https://github.com/paritytech/polkadot)
 //!
-//! Even those two just differ in the type of the `Tip` and `MultiAddress`.
-//! Statemint (Polkadot Asset Hub) seems to match the Polkadot config in almost all points, except for the `ExtrinsicParams`.
-//! Here the tips follow the same structure as for the default substrate node.
-//! We can now simply build the config for Statemint from the building blocks provided
-//! by [`PolkadotConfig`](crate::PolkadotConfig) and [`SubstrateConfig`](crate::SubstrateConfig) as shown below.
+//! These two configs are quite similar, and only differ slightly in the `MultiAddress` type, and in terms of the type of `Tip` provided
+//! as part of the `ExtrinsicParams`.
+//!
+//! Looking at the Statemint config, we can see that it is very similar to these. It ultimately uses the same signed extensions that
+//! Substrate uses, and otherwise uses the same types as Polkadot. So, we can create a config which just reuses these existing types:
 //!
 //! ```rust,ignore
-#![doc = include_str ! ("../../../../examples/parachain-example/src/statemint_config_composed.rs")]
+//! use subxt::{Config, PolkadotConfig, SubstrateConfig};
+//!
+//! pub enum StatemintConfig {}
+//!
+//! impl Config for StatemintConfig {
+//!     type Index = <PolkadotConfig as Config>::Index;
+//!     type Hash = <PolkadotConfig as Config>::Hash;
+//!     type AccountId = <PolkadotConfig as Config>::AccountId;
+//!     type Address = <PolkadotConfig as Config>::Address;
+//!     type Signature = <PolkadotConfig as Config>::Signature;
+//!     type Hasher = <PolkadotConfig as Config>::Hasher;
+//!     type Header = <PolkadotConfig as Config>::Header;
+//!     // this is the only difference to the PolkadotConfig:
+//!     type ExtrinsicParams = <SubstrateConfig as Config>::ExtrinsicParams;
+//! }
 //! ```
+//!
+//! This saves us a bunch of effort over creating our own `ExtrinsicParams` and so on, but is only applicable when such types are the
+//! same between the chain you're interested in interacting with, and either Substrate or Polkadot.
