Aurora was a experiment based on more recent themes. It tried some new layout things but it's EOL now.
Aurora uses the following libraries;
- Font Awesome 5
- Bootstrap v4.1
- JQuery (3.1.x)
- Aurora requires Ghost version 2.13.0+ to install and work as intended.
- Enable the Ghost API in the Ghost settings panel -> Labs -> Ghost API for the full featureset (although it's likely on by default if you run the latest version).
