I just recently joined the Wiki community with the recent launch of WikiVoyage. I have some experience working with iOS and would like to get work started on an open source mobile app for WikiVoyage. Before I begin, I want to know if WMF has any guidelines that need to be followed when beginning development. Is there a particular architecture or set of standards you guys use? Or are we free to "Plunge Forward" and make whatever kind of app we want?

One WikiVoyager has already developed an open-source Android app, which lives here: https://github.com/nicolas-raoul/OxygenGuide-Android and can be downloaded here: https://play.google.com/store/apps/details?id=org.github.OxygenGuide

If we build the app around that, can we use the WikiVoyage logo and branding to make it the official app?

Thanks in Advance!
