+# rbenv-alternatives
+
+This plugin allow you to add Ruby interpreters available through the Debian
+alternatives system into rbenv. This means you can install the different Ruby
+interpreters through APT on Debian and derivative distributions, and switch
+between them using rbenv.
+
+The Ruby interpreters installed via APT will become available to use with rbenv
+in addition to any other Ruby interpreter you may have installed into
+`~/.rbenv/versions` in any other way.
+
+This plugin also install hooks that configure Rubygems to install gems inside
+~/.rbenv/${version}/gems. This way you get completely separated Ruby
+environments.
+
+## Installation
+
+Just copy `rbenv-alternatives` into any directory in your `$PATH`, after
+installing and setting up rbenv itself.
+
+If you install rbenv through APT, then it will already bring this plugin with
+it:
+
+    # apt-get install rbenv
+
+## Usage
+
+    $ rbenv alternatives
+    $ rbenv versions
+      1.8.7-debian
+      1.9.2-debian
+    $ rbenv global 1.9.2-debian
+    $ rbenv version
+    1.9.2-debian (set by /home/terceiro/.rbenv/global)
+    $ ruby -v
+    ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-linux]
+
+Whenever you install a new Ruby interpreter, or uninstall a previously
+installed one, just run `rbenv alternatives` again and it will update your
+list of Debian-provided Ruby interpreters with rbenv.
