+### Gimme plugin for oh-my-zsh
+
+[Oh-my-zsh](https://github.com/robbyrussell/oh-my-zsh/) plugin making life a
+bit easier, when you use [gimme](https://github.com/travis-ci/gimme/) to manage
+[go](https://golang.org) installations.
+
+Provides following functions/aliases:
+  - ```go-versions```: Alias for ```gimme -l```
+  - ```install-gimme```: Download latest version of gimme to ~/bin
+  - ```load-go```: Load the go version specified by the first argument.
+    If called without argument, the 'stable' version will be loaded.
+  - ```remove-go```: Remove the go version specified by the first argument from
+    ~/.gimme/*
+  - Completions for ```gimme``` and ```load-go```
+
+```gimme``` is assumed to be in ```~/bin```, so make
+sure to add this folder to the $PATH variable.
