Ummm. there's no file/folder with that name, it's generated by the IDE Intellijd or phpstorm or similar... wich not everyone uses... so i don't see the point on merging this

[nueko]

Yea, that's just for users who use the IDE.

This file belongs in global .gitignore files since it's system specific.

Yeah I actually learned that from @GrahamCampbell a few years ago 😄 All IDE/OS specific ignores should go into the global gitignore
