 It can be used to manipulate git repositories at low level *(plumbing)* or high level *(porcelain)*, through an idiomatic Go API. It also supports several types of storage, such as in-memory filesystems, or custom implementations thanks to the [`Storer`](https://godoc.org/gopkg.in/src-d/go-git.v4/plumbing/storer) interface.

 Comparison with git
 -------------------
 
 *go-git* aims to be fully compatible with [git](https://github.com/git/git), all the *porcelain* operations are implemented to work exactly as *git* does.
 
-*git* is a humongous project with years of development by thousands of contributors, making it challenging for *go-git* implement all the features. You can find a comparison of *go-git* vs *git* in the [compatibility documentation](COMPATIBILITY.md).
