This will get you going with the latest version of rbenv and make it
easy to fork and contribute any changes back upstream.

1. Check out rbenv into `~/.rbenv`.

        $ cd
        $ git clone git://github.com/sstephenson/rbenv.git .rbenv

2. Add `~/.rbenv/bin` to your `$PATH` for access to the `rbenv`
   command-line utility.

        $ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile

3. Add rbenv init to your shell to enable shims and autocompletion.

        $ echo 'eval "$(rbenv init -)"' >> ~/.bash_profile

4. Restart your shell so the path changes take effect. You can now
   begin using rbenv.

        $ source ~/.bash_profile

5. Install [ruby-build](https://github.com/sstephenson/ruby-build) locally as a rbenv plugin:

        $ mkdir -p ~/.rbenv/plugins
        $ cd ~/.rbenv/plugins
        $ git clone git://github.com/sstephenson/ruby-build.git
        $ cd ~/.rbenv/plugins/ruby-build
        $ sudo ./install.sh

6. Install any [ruby version](https://github.com/sstephenson/ruby-build/tree/master/share/ruby-build) with the built in `rbenv-install` command:

        $ rbenv install 1.9.2-p290
