-## Changelog
+## Development
 
-The changelog is available [here](CHANGELOG.md).
+Project created by [Mattia Roccoberton](http://blocknot.es), thanks also to the good guys that opened issues and pull requests from time to time.
+
+A Docker dev setup is provided if you like to work with it:
+
+```sh
+# Run rails server on the dummy app (=> http://localhost:3000 to access to ActiveAdmin):
+make up
+# Enter in a console of the dummy app after it has been started:
+make console
+# Enter in a shell of the dummy app after it has been started:
+make shell
+# Run the linter on the project:
+make lint
+# Remove container and image after stopping the app:
+make cleanup
+```
+
+For more commands please check the [Makefile](Makefile).
