If you develop on windows and need cr/lf files, see this:
https://git-scm.com/book/en/v2/Customizing-Git-Git-Configuration#_formatting_and_whitespace
Git can handle this by auto-converting CRLF line endings into LF
when you add a file to the index, and vice versa when it checks out
code onto your filesystem. You can turn on this functionality with
the core.autocrlf setting. If you're on a Windows machine, set it
to true - this converts LF endings into CRLF when you check out code:
$ git config --global core.autocrlf true
