+The plugin provides a dedicated terminal interface for Claude Code CLI:
+
+- Uses [folke/snacks.nvim](https://github.com/folke/snacks.nvim) for terminal management
+- Creates a vertical split terminal with customizable size and position
+- Supports focus, toggle, and close operations
+- Maintains terminal state across operations

+### 6. Environment Integration
 
 The plugin manages the environment for Claude CLI:
 
 - Sets required environment variables:
   - `CLAUDE_CODE_SSE_PORT`: The WebSocket server port
   - `ENABLE_IDE_INTEGRATION`: Enabled flag
-- Provides terminal integration for launching Claude
+- Provides configuration for the terminal command

 - 🔍 Selection tracking to provide context to Claude
 - 🛠️ Integration with Neovim's buffer and window management
 - 📝 Support for file operations and diagnostics
-- 🖥️ Terminal integration for launching Claude with proper environment
+- 🖥️ Interactive vertical split terminal for Claude sessions (via `folke/snacks.nvim`)
 - 🔒 Automatic cleanup on exit - server shutdown and lockfile removal
 
 ## Requirements
 
 - Neovim >= 0.8.0
 - Claude Code CLI installed and in your PATH
 - Lua >= 5.1
+- **Required for terminal integration:** [folke/snacks.nvim](https://github.com/folke/snacks.nvim) - Terminal management plugin
 - Optional: plenary.nvim for additional utilities
 
+Note: The terminal feature requires Snacks.nvim to be installed and available. If not available, the terminal commands will display an error message, but the core Claude Code integration will still function.
