-combined in some way when relevant, e.g. an issue can be labelled *Bug*,
-*Confirmed* and *High priority* at the same time if it's a critical bug
-that was confirmed by several users, or *Feature request* and *Needs
-discussion* if it's a non-consensual feature request, or one that is not
+combined in some way when relevant, e.g. an issue can be labelled
+*Enhancement* and *Usability* at the same time if it's an issue to improve usability. 
+Or *Feature proposal* and *Discussion* if it's a non-consensual feature request, or one that is not
 precise enough to be worked on.

 Issues would typically correspond to only one topic, though it's not
 unthinkable to see issues that fit two bills. The general idea is that
 there will be specialized contributors teams behind all topics, so they
 can focus on the issues labelled with their team topic.
 
-Bug reports concerning the website or the documentation should not be
-filed in GitHub but in the appropriate tool in OpenProject, therefore
-such issues should be closed and archived once they have been moved to
-their rightful platform.
