Per https://help.github.com/articles/ignoring-files

From time to time there are files you don't want git to track. There are a few methods of telling git what files to ignore.

If you create a file in your repository named .gitignore git will use its rules when looking at files to commit. Note that git will not ignore a file that was already tracked before a rule was added to this file to ignore it. In such a case the file must be un-tracked, usually with git rm --cached filename

This file can be committed into the repository, thus sharing the rule list with any other users that clone the repository.
