+## What is ansible-ruby?
+
+It is an [Ansible](http://www.ansible.com/home) role to install a specific version of ruby without having to compile ruby on the machine you're setting up. It does this by using rvm under the hood.
+
+### What problem does it solve and why is it useful?
+
+I wasn't happy with any of the solutions that existed because they required you to either compile ruby on your server or they were not idempotent. Compiling ruby on a low end VPS/instance could easily take 10 minutes and during that time your CPU is going to be pegged at 100%.
+
+ansible-ruby solves this by using rvm to install 1 or more versions of ruby. It makes installing and upgrading ruby versions very easy.
+
+## Role variables
+
+The only variable you need to concern yourself about is `ruby_version` if you're happy with the default download and install path.
+
+```
+ruby_version: 2.1.1 # X.X.X-pXXX format
+
+ruby_temp_download_path: /usr/local/src
+ruby_rvm_install_path: /usr/local/rvm
+```
+
+## Example playbook
+
+For the sake of this mini example let's assume you have a group called **app** and you have a typical `site.yml` file.
+
+To use this role edit your `site.yml` file to look something like this:
+
+```
+---
+- name: ensure app servers are configured
+- hosts: app
+
+  roles:
+    - { role: nickjj.ruby, tags: ruby }
+```
+
+Let's say you want to edit the default version, you can do this by opening or creating `yourplaybook/group_vars/app.yml` and then making it look something like this:
+
+```
+---
+ruby_version: 2.0.0
+```
+
+## Installation
+
+`$ ansible-galaxy install nickjj.ruby`
+
+## Requirements
+
+Tested on ubuntu 12.04 LTS but it should work on other versions that are similar.
+
+## License
