 *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/gopkg.in/src-d/go-git.v4/plumbing/storer) interface.

 It's being actively developed since 2015 and is being used extensively by [source{d}](https://sourced.tech/) and [Keybase](https://keybase.io/blog/encrypted-git-for-everyone), and by many other libraries and tools.
 
@@ -21,7 +21,7 @@ Installation
 The recommended way to install *go-git* is:
 
 ```
-go get -u gopkg.in/src-d/go-git.v4/...
+go get -u github.com/go-git/go-git/v5/...
 ```
 
 > We use [gopkg.in](http://labix.org/gopkg.in) to version the API, this means that when `go get` clones the package, it's the latest tag matching `v4.*` that is cloned and not the master branch.

 ### and what this means ...
 *git* has a very well defined storage system, the `.git` directory, present on any repository. This is the place where `git` stores all the [`objects`](https://git-scm.com/book/en/v2/Git-Internals-Git-Objects), [`references`](https://git-scm.com/book/es/v2/Git-Internals-Git-References) and [`configuration`](https://git-scm.com/docs/git-config#_configuration_file). This information is stored in plain files.
 
-Our original **go-git** version was designed to work in memory, some time after we added support to read the `.git`, and now we have added support for fully customized [storages](https://godoc.org/gopkg.in/src-d/go-git.v4/storage#Storer).

 This means that the internal database of any repository can be saved and accessed on any support, databases, distributed filesystems, etc. This functionality is pretty similar to the [libgit2 backends](http://blog.deveo.com/your-git-repository-in-a-database-pluggable-backends-in-libgit2/)
