I managed to install Wikibase on a wiki farm (data repostory on one wiki and clients on the others). I'm now struggling to set up properties and using those to describe objects. For example, I created a page for a ratchet wrench and a property for mass, but I haven't figured out how to set the value of mass for the ratchet wrench.

Can you point me to a good tutorial?
