   where an extra bridge binary is acceptable.
 * Be able to import state from Ethereum mainnet.
 
-It consists of the following components:
-
-* **[pallet-evm](https://github.com/paritytech/frontier/tree/master/frame/evm)**:
-  EVM execution engine for Substrate.
-* **[pallet-ethereum](https://github.com/paritytech/frontier/tree/master/frame/ethereum)**: Emulation of full Ethereum block processing.
-* **rpc-ethereum**: Compatibility layer for web3 RPC methods.

-## Development notes
-
-Frontier is still work-in-progress. Below are some notes about the development.
-
-### Runtime
-
-A few notes on the EthereumRuntimeApi's runtime implementation requirements:
-
-- For supporting author rpc call, the FindAuthor trait must be implemented in an
-arbitrary struct. This implementation must call the authorities accessor in either
-Aura or Babe and convert the authority id response to H160 using
-pallet_evm::HashTruncateConvertAccountId::convert_account_id.
-
-The struct implementing FindAuthor is passed as the FindAuthor associated type's
-value for pallet_ethereum.
-
-An Aura example for this is available in the template's runtime (EthereumFindAuthor).
-
-- For supporting chain_id rpc call, a u64 ChainId constant must be defined.
-
-- For supporting gas_price rpc call, FeeCalculator trait must be implemented in an
-arbitrary struct. An example FixedGasPrice is available in the template's runtime.
-
-### Use local version of Substrate
-
-1. Override your local cargo config to point to your local substrate (pointing to your WIP branch): place `paths = ["path/to/substrate"]` in `~/.cargo/config`.
-2. You are good to go.
-
-Remember to comment out the override after it is done to avoid mysterious build issues on other repo.
+## Releases
+
+### Primitives
+
+Those are suitable to be included in a runtime. Primitives are structures shared
+by higher-level code.
+
+* `fp-consensus`: Consensus layer primitives.
+  ![Crates.io](https://img.shields.io/crates/v/fp-consensus)
+* `fp-evm`: EVM primitives. ![Crates.io](https://img.shields.io/crates/v/fp-evm)
+* `fp-rpc`: RPC primitives. ![Crates.io](https://img.shields.io/crates/v/fp-rpc)
+* `fp-storage`: Well-known storage information.
+  ![Crates.io](https://img.shields.io/crates/v/fp-storage)
+
+### Pallets
+
+Those pallets serve as runtime components for projects using Frontier.
+
+* `pallet-evm`: EVM execution handling.
+  ![Crates.io](https://img.shields.io/crates/v/pallet-evm)
+* `pallet-ethereum`: Ethereum block handling.
+  ![Crates.io](https://img.shields.io/crates/v/pallet-ethereum)
+* `pallet-dynamic-fee`: Extends the fee handling logic so that it can be changed
+  within the runtime.

+
+### EVM Pallet precompiles
+
+Those precompiles can be used together with `pallet-evm` for additional
+functionalities of the EVM executor.
+
+* `pallet-evm-precompile-simple`: Four basic precompiles in Ethereum EVMs.
+  ![Crates.io](https://img.shields.io/crates/v/pallet-evm-precompile-simple)
+* `pallet-evm-precompile-blake2`: BLAKE2 precompile.
+  ![Crates.io](https://img.shields.io/crates/v/pallet-evm-precompile-blake2)
+* `pallet-evm-precompile-bn128`: BN128 precompile.
+  ![Crates.io](https://img.shields.io/crates/v/pallet-evm-precompile-bn128)
+* `pallet-evm-precompile-ed25519`: ED25519 precompile.
+  ![Crates.io](https://img.shields.io/crates/v/pallet-evm-precompile-ed25519)
+* `pallet-evm-precompile-modexp`: MODEXP precompile.
+  ![Crates.io](https://img.shields.io/crates/v/pallet-evm-precompile-modexp)
+* `pallet-evm-precompile-sha3fips`: Standard SHA3 precompile.
+  ![Crates.io](https://img.shields.io/crates/v/pallet-evm-precompile-sha3fips)
+* `pallet-evm-precompile-dispatch`: Enable interoperability between EVM
+  contracts and other Substrate runtime components.
+  ![Crates.io](https://img.shields.io/crates/v/pallet-evm-precompile-dispatch)
+
+### Client-side libraries
+
+Those are libraries that should be used on client-side to enable RPC, block hash
+mapping, and other features.
+
+* `fc-consensus`: Consensus block import.
+  ![Crates.io](https://img.shields.io/crates/v/fc-consensus)
+* `fc-db`: Frontier-specific database backend.
