Hallo,
I started a document that explains the needed steps on how to add "art" (music, patches, images) to our community area. It is a wiki page and I was a bad guy again and used studdly caps in the file's name as is usually the case with WikiPages. I'm not sure if our informal style guide should allow this, but I think for Wiki pages it might be okay.
But I was even badder and added this documentation to the community folder, not under documentation. I'm not sure about this, though. On one hand it's a doc item that strongly belongs to the community area, but then it also might be good to have site docs under documentation.
Well, anyway: you can find the new doc at:
