The step-by-step tutorial in README-source.adoc to create a project from scratch contains outdated information that doesn't match the actual source code. This creates confusion for developers following the quickstart guide.

Key Issues:

1. Missing critical MicroProfile Config properties (group.id, auto.offset.reset)
2. Outdated persistence.xml (version 2.2 → 3.0, wrong namespace)
3. The instruction to implement a classes lead users to create a different implementation then prepared classes in the src folder.
