+### Session 03: Behind the Scenes
+
+In order to run applications using `kraft`, both locally and with `kraftcloud`, we need to build a minimal required filesystem for the application we want to run.

+In case there are issues with KraftCloud / KraftKit, you can use Docker to see if everything is in the right place and to assist in debugging.
