Hi Lukas,
the vagrant-setup is almost working...
I can open the client and the repo, but there is nothing in it... The instruction says: "Both repo and client contain the chemical elements as test data"
I think this concerns to the central test database. Try http://wikidata-test-repo.wikimedia.de/wiki/Q344 which is really an element. I would be surprised if any newly installed software contained actual data.
I don't care about actual data. But the Wikidata-instance created by vagrant has no data at all and I have no idea how to create a new item.
Sorry for this - puppet sometimes runs into a timeout problem. I hope to fix this today!
Best, Silke
