+
+> Implementation of [multibase](https://github.com/multiformats/multibase) -self identifying base encodings- in Go.
+
+
+## Install
+
+`go-multibase` is a standard Go module which can be installed with:
+
+```sh
+go get github.com/multiformats/go-multibase
+```
+
+Note that `go-multibase` is packaged with Gx, so it is recommended to use Gx to install and use it (see Usage section).
+
+## Usage
+
+This module is packaged with [Gx](https://github.com/whyrusleeping/gx). In order to use it in your own project it is recommended that you:
+
+```sh
+go get -u github.com/whyrusleeping/gx
+go get -u github.com/whyrusleeping/gx-go
+cd <your-project-repository>
+gx init
+gx import github.com/multiformats/go-multibase
+gx install --global
+gx-go --rewrite
+```
+
+Please check [Gx](https://github.com/whyrusleeping/gx) and [Gx-go](https://github.com/whyrusleeping/gx-go) documentation for more information.
+
+## Maintainers
