This is a side affect of running the autoformatter - it still gets rendered as a numeric sequence (1, 2, 3, etc)

We should add instructions on how to modify the CI for the hotfix branch before adding the actual fix (remove testing on irrelevant sdk versions, add testing on relevant sdk versions if needed, remove sending notifications, etc)

Done!

Can we add general description of the steps, so it is clear what are we trying to do? The steps above could move under the general step as sub-steps (so the user can chose to do them differently if needed, for example, via git commands)

For example

1. create a branch off the release that needs a hotfix
   a. In the Github UI's
   commit history view,
   find the commit that prepared the release of DWDS that you would like to
   hotfix.
   b. Click on < > ("Browse the repository at this point in history").
   ...
2. Update CI for the new branch
   a ...
3. Add the fix
   a.
4. publish
   a.

Done!

LGTM with small change request - the sequential numbering is still showing all 1's, can we update it to 1, 2, 3...?

This is a change made by the Markdown auto-formatter. You can create a sequentially ordered list using all 1s. That way MD automatically handles the numbering.
