+Running Proxy
+```
+You can run proxy using the `launch.json` shipped for this component. Please note that proxy will rely on you creating and configuring right environment values in an env file called `bob.env`.
+
+To start proxy in debugging mode simply select `bob proxy` from the debugging menu of vs code.
