sudo docker ps
```

You should see something like:

* If shortcodes are **not rendering**:

  1. Go to **Appearance → Themes**
  2. Activate **Twenty Twenty-Three** (or another default theme).


* If navigating to `http://localhost:8000/` says **Database Not Connected**:
  1. Wait a minute or two for the Database to finish setting up
