+
+### Configuration Options Explained
+
+#### Server Options
+
+- **`port_range`**: Port range for the WebSocket server that Claude connects to
+- **`auto_start`**: Whether to automatically start the integration when Neovim starts
+- **`terminal_cmd`**: Override the default "claude" command (useful for custom Claude installations)
+- **`log_level`**: Controls verbosity of plugin logs
+
+#### Selection Tracking
+
+- **`track_selection`**: Enables real-time selection updates sent to Claude
+- **`visual_demotion_delay_ms`**: Time to wait before switching from visual selection to cursor position tracking
+
+#### Connection Management
+
+- **`connection_wait_delay`**: Prevents overwhelming Claude with rapid @ mentions after connection
+- **`connection_timeout`**: How long to wait for Claude to connect before giving up
+- **`queue_timeout`**: How long to keep queued @ mentions before discarding them
+
+#### Terminal Configuration
+
+- **`split_side`**: Which side to open the terminal split (`"left"` or `"right"`)
+- **`split_width_percentage`**: Terminal width as a fraction of screen width (0.1 = 10%, 0.5 = 50%)
+- **`provider`**: Terminal implementation to use:
+  - `"auto"`: Try snacks.nvim, fallback to native
+  - `"snacks"`: Force snacks.nvim (requires folke/snacks.nvim)
+  - `"native"`: Use built-in Neovim terminal
+- **`show_native_term_exit_tip`**: Show help text for exiting native terminal
+- **`auto_close`**: Automatically close terminal when commands finish
+
+#### Diff Options
+
+- **`auto_close_on_accept`**: Close diff view after accepting changes with `:w` or `<leader>da`
+- **`show_diff_stats`**: Display diff statistics (lines added/removed)
+- **`vertical_split`**: Use vertical split layout for diffs
+- **`open_in_current_tab`**: Open diffs in current tab instead of creating new tabs

-### Terminal Auto-Close Behavior
-
-The `auto_close` option controls what happens when Claude commands finish:
-
-**When `auto_close = true` (default):**
-
-- Terminal automatically closes after command completion
-- Error notifications shown for failed commands (non-zero exit codes)
-- Clean workflow for quick command execution
