 1. **Launch Claude**: Run `:ClaudeCode` to open Claude in a split terminal
 2. **Send context**:
    - Select text in visual mode and use `<leader>as` to send it to Claude
-   - In `nvim-tree`/`neo-tree`/`oil.nvim`, press `<leader>as` on a file to add it to Claude's context
+   - In `nvim-tree`/`neo-tree`/`oil.nvim`/`netrw`, press `<leader>as` on a file to add it to Claude's context
 3. **Let Claude work**: Claude can now:
    - See your current file and selections in real-time
    - Open files in your editor
