 This is a demo app to show how simple it is to integrate [Avo](https://avohq.io) in your app.
 
 Have a look at the [/avo](/app/avo) directory to find the resources, filters and actions.
+
+### Install locally
+
+This should be a pretty straighforward Rails install. The app has seeds and everything it needs.
+
+```bash
+bundle install
+
+bin/rails db:setup
+
+bin/rails serve
+```
