The file will have its original line endings in your working directory. warning: LF will be replaced by CRLF in ...

Generally in the Unix your end of a line is always represented with the line feed (LF). And in windows the line is always represented with the carriage return (CR) and your end of line (LF) thus (CRLF). So when you have code from git that was uploaded by the unix system then it will only have the LF.

If you want to turn warning off then you can do it by typing a below command in your git command line

git config core.autocrlf true
