## Upgrading
When a new version comes out, sometimes you want to upgrade your instance right away. Here's a checklist what to do:

2. Make a backup of your currently working instance. This includes both the PhotosAPI and the database
3. Download the latest version using git (`git pull` if you cloned the repo in the past) or from the releases
