Cool. Maybe OsmAnd could implement it in the future.

There should be an easy to understand guide, that's meant for mappers and not only for developers. I've written a tutorial for the basics[1] but everything should be described clearly (not necessarily example-based).

Because I know that by saying "there should be" on the mailing lists nothing will happen, I created a draft in my userspace[2]. I invite everyone that is interested in clearing this mess to join me. You can just change the page, no need to ask me for permission.

There is too much information on the page, so I moved some content to subpages.
