+## Development Guide
+
+Most of the interesting bits are happening in the server so you'll probably want
+to head over to the [development guide][server-dev-guide] to see the development
+flow for the server.
+
+If not, here's how to work on the Atom client.
+
+```bash
+git clone git@github.com:mads-hartmann/ide-bash && cd ide-bash
+npm install
+apm link
+```
+
+If you want to inspect the communication between the Atom and the Bash language
+server then open the Developer Tools in Atom and execute the following piece of
+code in the Console.
+
+```javascript
+atom.config.set('core.debugLSP', false)
+```
+
+Reload the window and you should see all the messages.
