+### Troubleshooting
+
+If you encounter issues while using OpenHands in Zed with the ACP plugin, you can access detailed debug logs:
+
+1. Open the command palette with `Cmd+Shift+P` (Mac) or `Ctrl+Shift+P` (Windows/Linux)
+2. Type and select `acp debug log` to view detailed debug information
+3. Review the logs for any errors or warnings
+4. Restart a new conversation to reload connections after making configuration changes
+
+The debug logs can help you identify configuration issues, connection problems, or errors in your setup.
+
+<Note>
+If you encounter persistent issues, verify that OpenHands CLI is properly configured (see [Prerequisites](#prerequisites)) and that all server commands are executable from your system PATH.
