 ## Overview
 
-The `WebSocketAccountSubscriberV2` class provides the same interface as the original `WebSocketAccountSubscriber` but uses gill's modern JavaScript/TypeScript client library for Solana blockchain interactions.
-
-## Key Benefits
-
-1. **Modern Library**: Uses gill, which is built on top of Anza's `@solana/kit` (formerly web3.js v2)
-2. **Better Performance**: Optimized RPC calls and WebSocket subscriptions
-3. **Type Safety**: Full TypeScript support with better type definitions
-4. **Compatibility**: Drop-in replacement for existing `WebSocketAccountSubscriber`
-
-## Installation
-
-First, install the gill dependency:
-
-```bash
-npm install gill
-```

 2. **WebSocket Subscriptions**: Uses gill's `rpcSubscriptions` for real-time updates
 3. **Address Handling**: Converts `PublicKey` to gill's `Address` type for compatibility
 4. **Response Formatting**: Converts gill responses to match the expected `AccountInfo<Buffer>` format
-
-### Fallback Implementation
-
-The current implementation includes fallback code that uses the original web3.js methods when gill is not available. This ensures backward compatibility while the gill integration is being set up.
-
-## Migration Guide
-
-To migrate from `WebSocketAccountSubscriber` to `WebSocketAccountSubscriberV2`:
-
-1. **Install gill**: `npm install gill`
-2. **Update imports**: Replace the import statement
-3. **Uncomment gill code**: Remove the TODO comments and uncomment the gill-specific code
-4. **Test thoroughly**: Ensure all functionality works as expected
-
-## Example with Gill Integration
-
-Here's how the implementation looks when fully integrated with gill:
-
-```typescript
-// Constructor with gill initialization
-const rpcUrl = (this.program.provider as AnchorProvider).connection.rpcEndpoint;
-const { rpc, rpcSubscriptions } = createSolanaClient({
-	urlOrMoniker: rpcUrl,
-});
-this.rpc = rpc;
-this.rpcSubscriptions = rpcSubscriptions;
-
-// Subscribe using gill's WebSocket
-const accountAddress = this.accountPublicKey.toBase58() as Address;
-this.listenerId = this.rpcSubscriptions
-	.accountNotifications(accountAddress)
-	.subscribe(
-		{
-			commitment: this.commitment,
-			encoding: 'base64',
-		},
-		(notification) => {
-			this.handleRpcResponse(notification.context, notification.value);
-		}
-	);
-
-// Fetch using gill's RPC
-const rpcResponse = await this.rpc
-	.getAccountInfo(accountAddress, {
-		commitment: this.commitment,
-		encoding: 'base64',
-	})
-	.send();
-```
-
-## Benefits of Using Gill
-
-1. **Performance**: Better connection management and optimized RPC calls
-2. **Reliability**: Improved error handling and reconnection logic
-3. **Modern APIs**: Uses the latest Solana JavaScript client libraries
-4. **Type Safety**: Better TypeScript support and type definitions
-5. **Future-Proof**: Built on the foundation of Solana's modern tooling
-
-## Troubleshooting
-
-### Common Issues
-
-1. **Module not found**: Ensure gill is installed: `npm install gill`
-2. **Type errors**: Make sure TypeScript can find gill's type definitions
-3. **Connection issues**: Verify the RPC URL is accessible and supports WebSocket connections
-
-### Debug Mode
-
-Gill supports debug mode for troubleshooting:
-
-```typescript
-// Enable debug mode
-process.env.GILL_DEBUG = 'true';
-
-// Or in browser console
-window.__GILL_DEBUG__ = true;
-```
