 Teamocil is a simple tool used to automatically create sessions, windows and splits in [tmux](http://tmux.sourceforge.net/) with YAML files.
 
+[![Build Status](https://secure.travis-ci.org/remiprev/teamocil.png)](http://travis-ci.org/remiprev/teamocil)
+
 ## Usage
 
-    $ gem install teamocil
-    $ mkdir ~/.teamocil
-    $ teamocil --edit sample
-    $ tmux
-    $ teamocil sample
+```bash
+$ gem install teamocil
+$ mkdir ~/.teamocil
+$ teamocil --edit sample
+$ tmux
+$ teamocil sample
+```
 
 ## Options
 
 * `--here` opens the session in the current window, it doesn’t create an empty first window.
 * `--layout` takes a custom file path to a YAML layout file.
 * `--edit` opens the layout file (whether or not `--layout` is used) with `$EDITOR`.
+* `--list` lists all available layouts.

 ## Todo list
 
-* Support tmux options for windows and splits (eg. `synchronize-panes`)
-* Making sure the layout is valid before executing it
-* Refactor the `Layout` class to make it “test-friendly”
+* Making sure the layout is valid before executing it (ie. throw exceptions).
+* Add more specs.
