at some point we could also think displaying these dynamically: https://contrib.rocks/preview?repo=inovex%2Fscrumlr.io

although this has the disadvantage of not showing designers since they don't have any code commits

I think it's pretty nice to let people add themselves to our team members list since it's also a check that he can push to the repo as a first PR :)

agreed!
