You can create `app.yml` manually (there is a template in `/var/discourse/samples/standalone.yml`) – but if you already bootstrapped and want to downgrade, this is easy as long _as you are willing to lose your data_. Simply update `app.yml`, then run this:

```bash
cd /var/discourse/
./launcher stop app
rm -rf shared/standalone/ # wipe shared volume
./launcher rebuild app

```

> ⚠ Executing these commands will **completely reset Discourse**! All content, users and settings will be deleted.
