# Editing Discourse Configuration

Edit `app.yml`:

nano containers/app.yml
|
||||

(We recommend Nano because it works like a typical GUI text editor, just use your arrow keys. Hit <kbd>Ctrl</kbd><kbd>O</kbd> then <kbd>Enter</kbd> to save and <kbd>Ctrl</kbd><kbd>X</kbd> to exit. However, feel free to choose whatever text editor you like.)
|

|

- Edit as desired, but at minimum you must set `DISCOURSE_DEVELOPER_EMAILS` and `DISCOURSE_HOSTNAME`.
