```
[core]
	repositoryformatversion = 0
	filemode = true
	bare = false
	logallrefupdates = true
	ignorecase = true
	precomposeunicode = true
[remote "origin"]
	url = *****
	fetch = +refs/heads/*:refs/remotes/origin/*
[branch "develop"]
	remote = origin
	merge = refs/heads/develop
[pre-commit]
	checks = [:whitespace, :jshint, :debugger]
```
