Around 1 year ago, I attempted to contribute firstly to this project.
I observed that the main homepage lists relib - while nearly all the other languages still listed newlib.
I had encountered issue with Gitlab and after around a full hour of trying to change newlib into relib, I gave up.
In 6 years of contributing to open source, I barley ever encountered such a complicated process, although I never actually committed to Gitlab - and swore I will never do it again.
Now I see, that this issue still persists - the wording is still incorrect and it shows me, how important it is to make contributing actually easily accessible.
Just a hint, maybe someone likes to change the translation.
And ideally, think about some other option to contribute, like Gitea.
