I couldn’t find this in the documentation: When using version control, which files should I include and which exclude? Especially when both OSX and Windows are used for development. The project has Blueprints and C++ source files, and therefore need to be compiled using VS and Xcode.
HI,
Check out this answer:
Thanks for your reply! That was simple enough, but I would still prefer seeing it in the documentation. 
Funny you should mention that, there is an official docs page for this (and a while lot more) that I have been putting together recently. It should be up as soon as it has had some editorial love from the docs team
