FATE Core System Structure

[Maidhc O Casain]

So... I'm considering converting a Pathfinder campaign/Adventure Path to FATE Core, and would love to put it into Realm Works.

I started looking at creating a system structure for FATE Core, and can't really find any instructions for creating one's own system structure "from scratch." The Developer's Diary talks about it, but in the one article written it just says that creating custom structure is a topic for another article.

Anyone got any advice for me? Links to documentation or tutorials? Step-by-Step, starting from the very beginning, would be awesome, but I'll take anything I can get...

Thanks in advance!
