Revert this to [example-app] and scroll down to the end of the README; there, you will find the link that needs to be modified.

@r2dedios We don't need both example apps. We should delete the old busybox one while PRing the new pacman one.

Also, the previous example app folder structure was:

• doc/ - All documentation-related, i.e. images and markdowns.
• doc/ExampleDRApp.md - The example app documenation.
• doc/example-app - The example app manifests.

The new example app diverged from this structure and was placed in the project's root. Should we adapt to the previous structure to be consistent with the rest of the pattern documentation?

For the failing markdown lint, you can run this locally to work through the errors:

podman run --privileged \
  -e RUN_LOCAL=true \
  -e DEFAULT_BRANCH=main \
  -e VALIDATE_MARKDOWN=true  \
  -e VALIDATE_NATURAL_LANGUAGE=true  \
  -v $PWD:/tmp/lint \
  ghcr.io/super-linter/super-linter:latest

@r2dedios I just noticed you created this PR from the branch pattern-final-fixes, which was already merged here: #5. (That explains 107 commits...).

You should refresh your fork, create a new branch from the main one, and only include commits relevant to this PR.
