Tip: Write <hr/> in comments here to insert horizontal rulers. Do not write <hr>.

a couple of dashes also works, e.g.

---

3 dashes

---

2 dashes

Do we need an app or can we just use a link for now?

Currently, https://docs.typo3.org/services/GithubPullRequests/ does not work at all, we have lots of other things to do, would be an easy solution for now until someone has the time to put effort into this:

https://github.com/pulls?q=is%3Aopen+is%3Apr+archived%3Afalse+org%3ATYPO3-Documentation+sort%3Acreated-asc

org:TYPO3-Documentation
will show all PR in TYPO3-Documentation.
