 No one likes dead links. Therefore, we check the internal and external links within the markdown
 source files. For that, the script `util/check-links.sh` and/or the tool
 [markdown-link-check](https://github.com/tcort/markdown-link-check) can be used.

-### Check Pages Structure
+## Check Pages Structure
 
 The script `check-no-floating.sh` contains two checks. It first checks the hierarchy depth of the
 pages structure. By design, no page in the documentation should be lower than four levels w.r.t. top
 level, i.e., landing page. Secondly, the script tests if every markdown file is included in the
 navigation section within the `mkdocs.yaml` file of this project.
