+    \subsection{Smart Eating Project}
         Each push to the repository executes a CI pipeline, which in turn builds docker images for all project components.
         These docker images are then published to the Gitlab internal registry.
 
-        The unit tests are also automatically executed in this pipeline.

     \subsection{Documentation}
         Each push to the documentation repository triggers a build of the documentation.
         As many diagrams are diagrams-as-code, these diagrams are built first and then consumed when building the documentation.
