 # `@ai16z/plugin-cosmos`
 
-This plugin provides actions and providers for interacting with Cosmos compatible chains.
+This plugin provides actions and utilities for interacting with Cosmos-compatible blockchains.
 
 ---
 
+## Development
+
+Prepare Eliza according to [README](../../README.md)
+ Add variables required for `@ai16z/plugin-cosmos` :
+ ```
+COSMOS_RECOVERY_PHRASE=your recovery phrase words
+COSMOS_AVAILABLE_CHAINS=chain1,chain2,chain3
+  ```
+
+Run Eliza with `@ai16z/plugin-cosmos` character:
+```
+pnpm run dev --characters="../cosmosHelper.character.json"
+```
+
 ## Configuration
 
 ### Default Setup
 
-### Adding Support for Other Chains
+To start using the plugin, you need to provide your **Cosmos account recovery phrases** and the list of **available chains**. Add the following to your `.env` file:
+
+
+```env
+COSMOS_RECOVERY_PHRASE=your recovery phrase words
+COSMOS_AVAILABLE_CHAINS=chain1,chain2,chain3
+```
+Ensure that the chain names in `COSMOS_AVAILABLE_CHAINS` match the identifiers from the [chain-registry](https://github.com/cosmos/chain-registry) library for compatibility.
+
+
+### Using the Cosmos Helper Character
+
+The plugin includes a pre-configured character, `cosmosHelper.character.json`, optimized for Cosmos-related operations. This character enhances interaction by:
+
+- Handling repeated prompts effectively.
 
-## Provider
+- Requesting confirmation before executing detected actions.
+
+To use the character, pass it with the `--characters` flag:
+
+```bash
+--characters='../characters/cosmosHelper.character.json'
+```
+
+---
+
+### Custom chain configuration
+Plugin allows you to pass you custom chain config to `createCosmosPlugin` function invoked in `../agent/src/index`.
+
+Your custom configuration fulfills the interfaces from `chain-registry`
+```
+import  type { assets, chains } from  "chain-registry";
+
+export  interface  ICosmosPluginCustomChainData {
+	chainData: (typeof  chains)[number];
+	assets: (typeof  assets)[number];
+}
+
+export  interface  ICosmosPluginOptions {
+	customChainData?: ICosmosPluginCustomChainData[];
+}
+```
 
 ## Actions
 
-### Transfer
+### Token Transfer
+
+This plugin supports a token transfer action, which allows users to transfer tokens between addresses on Cosmos-compatible blockchains. The action prompts for confirmation to ensure secure execution.
+
+#### Example Prompts
+
+Below are examples of how the transfer action can be initiated and confirmed:
+
+**Example**
+
+1. User input:
+
+```
+Make transfer 0.0001 ATOM to cosmos1nk3uuw6zt5t5aqw5fvujkd54sa4uws9xv465ad on cosmoshubtestnet.
+```
+
+2. Plugin response:
+
+```
+Do you confirm the transfer action?
+```
+
+3. User confirmation:
+
+```
+Yes
+```
+
+4. Action executed.
