 After stopping the script it is necessary to clear the environment using the command described in [Shutting down](#Shutting-down). This is necessary as on a new run of the scripts (with autopeering or not) the wallet address url will differ.
 
+### Debugging
+
+Debuggers for the services are exposed on the following ports:
+
+| IP and Port    | Services                |
+| -------------- | ----------------------- |
+| 127.0.0.1:9229 | Cloud Nine Backend      |
+| 127.0.0.1:9230 | Cloud Nine Auth         |
+| 127.0.0.1:9231 | Happy Life Bank Backend |
+| 127.0.0.1:9232 | Happy Life Bank Auth    |
+
+To use these debuggers with a chromium browser:
+
+- go to `chrome://inspect` in chromium browser
+- Click "Configure" add the IP addresses and ports detailed above
+- start docker containers
+- click "inspect" on the service you want to debug to open the chromium debugger
+
+You can either trigger the debugger by adding `debugger` statements in code and restarting, or by adding breakpoints directly in the chromium debugger after starting the docker containers.
+
+For more ways to connect to these debuggers, see the Node docs for debugging: https://nodejs.org/en/learn/getting-started/debugging
