@Tobias Gritschacher (WMDE) – is the outdated box still relevant after your changes?
Topic on Talk:Wikibase/Installation/Advanced configuration
@Jan Dittrich (WMDE) Yes, I've just moved everything that was more advanced than the basic setup from the Wikibase Repository & Client extension manuals as it was. I've not made any changes to this stuff yet. We need to go through all the different configuration options and clean up the documentation. See https://phabricator.wikimedia.org/T165973
