Sophie and I try to find a workflow for the translation extension on the
wiki. I did a test with the ReleaseNotes/6.2 and marked it to get the
process as fast as possible online for that page (before more translated
pages get created for this page or the page gets more content).
at the very top there is a mark how much content is already translated,
for the german page:
This page is a translated version of the page ReleaseNotes/6.2 and the
translation is 48% complete.
