This is also nothing I prefere for a final solution. But I got stucked
when I was looking for a way to add the actual documentation because I
wanted to add it into a cleaned-up environment. But I don't have the
possibility at the moment to cleanup the existing timer documentation
right away with all its aspects (content, formatting, referencing,
location below Documentation,... ).

So I had those options:

1. wait until I have time for all this before publishing the new
   documentation -> not an option because I don't know when there is
   time to do all those things in one go

2. Put the new documentation below the existing one and ignore the rest
   silently (maybe someone else will clean it up someday) -> not an
   option because it suggests that the new documentation structure is
   just ignored

3. Just move the old documentation without revisiting it -> not an
   option because there might be outdated information and then it
   doesn't has a benefit for the reader

4. Add a warning banner at the existing documentation and prepare
   everything to get the timer documentation to the proper place and
   create a place for timer documentation below the current structure.

The benefit of 4. for me is, that there is this warning banner at the
top. So this suggests the reader, that this has to be revisited before
relying on it for 100%. This banner might also remind the original
author/technically deep involved developer that this should be
updated.

If there is a better way to go, please let me know!

Thanks,

        Anna-Maria
