Just thought I'd jump in here and give you a link to githubs training page. Seeing as this project would benefit 100% from community involvement I think using git would be great, so people can help updating it and as well maintaining it in the future. The API calls will change many times and you might not even be interested after a while.
So, I see you have not used git before, but you seem interested, if you go to this page they have set up a very easy guide on how to use it, won't have to deal with harddrives crashing either if you push your updates to the remote repo
Been looking for a wow api package for Sublime for a while, so thanks for developing this
