*go-git* is a highly extensible git implementation library written in **pure Go**.
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/github.com/go-git/go-git/v5/plumbing/storer) interface.

After the legal issues with the [`src-d`](https://github.com/src-d) organization, the lack of update for four months and the requirement to make a hard fork, the project is **now back to normality**.
The project is currently actively maintained by individual contributors, including several of the original authors, but also backed by a new company `gitsigth` where `go-git` is a critical component used at scale.
