-# Feature Matrix
-This section gives more details about the features and implementation status 
-of Hermes in comparison with the [cosmos-go-relayer].
+# Features
+
+This section includes a summary of the supported and planned features. It also includes a feature matrix which compares `hermes` to the [cosmos-go-relayer].
+
+> **Cosmos SDK & IBC compatibility:**
+> Hermes supports Cosmos SDK chains implementing the [IBC protocol v1][ibcv1-proto] protocol specification.
+> Cosmos SDK versions `0.41.3` through `0.45.x` are officially supported.
+> IBC-go versions `1.1.*` thorough `3.*` are officially supported.
+> In case Hermes finds an incompatible SDK or IBC-go version, it will output a log warning upon initialization as part of the `start` command or upon `health-check` command.
+
+---
+
+## Supported Features
+
+- Basic features
+    - Create and update clients.
+    - Refresh clients to prevent expiration.
+    - Establish connections with new or existing clients.
+    - Establish channels with new or existing connection.
+    - Channel closing handshake.
+    - Relay packets, acknowledgments, timeout and timeout-on-close packets, with zero or non-zero delay.
+    - Queries for all objects.
+- Packet relaying over:
+    - multiple paths, for the chains in `config.toml`.
+- Restart support:
+    - Clear packets.
+    - Resume channel handshake if configured to relay `all`.
+    - Resume connection handshake if configured to relay `all`.
+- Client upgrade:
+    - Upgrading clients after a counterparty chain has performed an upgrade for IBC breaking changes.
+- Packet delay:
+    - Establish path over non-zero delay connection.
+    - Relay all packets with the specified delay.
+- Interchain Accounts & Interchain Security
+- Monitor and submit misbehaviour for clients
+    - Monitor client updates for misbehaviour (fork and BFT time violation).
+    - Submit misbehaviour evidence to the on-chain IBC client.
+    > Misbehaviour submission to full node not yet supported.
+- Individual commands that build and send transactions for:
+    - Creating and updating IBC Tendermint light clients.
+    - Sending connection open handshake messages.
+    - Sending channel open handshake messages.
+    - Sending channel closing handshake messages.
+    - Initiating a cross chain transfer (mainly for testing).
+    - Relaying sent packets, acknowledgments and timeouts.
+    - Automatically generate a configuration file from the [chain-registry](https://github.com/cosmos/chain-registry)
+    - Client upgrade.
+- Channel handshake for existing channel that is not in `Open` state.
+- Connection handshake for existing connection that is not in `Open` state.
+- Telemetry support.
+
+## Upcoming / Unsupported Features
+
+Planned features:
+- Interchain Queries
+- Non-SDK support
+- Relay from all IBC events, including governance upgrade proposal
+- Dynamic & automatic configuration management

+# Help command
+
+The CLI comprises a special `help` command, which accepts as parameter other commands, and provides guidance on what is the correct way to invoke those commands.
+
+> __NOTE__: This special `help` command is preferred as it will display the full help
+> message.
+
+For instance,
+
+```shell
+hermes help create
+```
+
+will provide details about all the valid invocations of the `create` CLI command.
+
+```
+USAGE:
+    hermes create <SUBCOMMAND>
+
+DESCRIPTION:
+    Create objects (client, connection, or channel) on chains
+
+SUBCOMMANDS:
+    channel       Create a new channel between two chains
+    client        Create a new IBC client
+    connection    Create a new connection between two chains
+    help          Print this message or the help of the given subcommand(s)
+```
+
+This can provide further specific guidance if we add additional parameters, e.g., 
+
+```shell
+hermes help create channel
+```
+
+```shell
+USAGE:
+    hermes create channel [OPTIONS] --a-chain <A_CHAIN_ID> --a-connection <A_CONNECTION_ID> --a-port <A_PORT_ID> --b-port <B_PORT_ID>

+    hermes create channel [OPTIONS] --a-chain <A_CHAIN_ID> --b-chain <B_CHAIN_ID> --a-port <A_PORT_ID> --b-port <B_PORT_ID> --new-client-connection
+
+DESCRIPTION:
+    Create a new channel between two chains.
+
+    Can create a new channel using a pre-existing connection or alternatively, create a new client and a
+    new connection underlying the new channel if a pre-existing connection is not provided.
+
+OPTIONS:
+        --channel-version <VERSION>
+            The version for the new channel
+
+            [aliases: chan-version]
+
+        --new-client-connection
+            Indicates that a new client and connection will be created underlying the new channel
+
+            [aliases: new-client-conn]
+
+        --order <ORDER>
+            The channel ordering, valid options 'unordered' (default) and 'ordered'
+
+            [default: ORDER_UNORDERED]
+
+        --yes
+            Skip new_client_connection confirmation
+
+FLAGS:
+        --a-chain <A_CHAIN_ID>
+            Identifier of the side `a` chain for the new channel
+
+        --a-connection <A_CONNECTION_ID>
+            Identifier of the connection on chain `a` to use in creating the new channel
+
+            [aliases: a-conn]
+
+        --a-port <A_PORT_ID>
