+### Proxy debugging note
+If you are using ES6 Proxy in your Node app, you may notice the debugger crash. This is due to a bug in Node/V8's deprecated debugging protocol. As a workaround, we recommend using our debug adapter that uses their new debugging protocol, which you can opt-in to by setting `"type": "node2"` in your `launch.json` config. It's supported for Node v6.3+. This issue is tracked in [Microsoft/vscode#12749](https://github.com/Microsoft/vscode/issues/12749).
