Can't find or use San Francisco in apps like Sketch I understand that the font is only available for developers, but i'm not one at the moment, but when trying to use facebook sketch template for ios9 i get a prompt saying this 



My question is if there is a way a round this without messing with the system default fonts as this repo does https://github.com/supermarin/YosemiteSanFranciscoFont or is it the only way?

system: macbook running osx el-capitan
Initially, you had to have a developer account. Now anyone can download the font at https://developer.apple.com/fonts/ and install them on your system (using the font book app). 

Now Sketch is satisfied and it won't give you any warnings about the missing San Francisco font.
