 ## Usage
 
 A contrived example of starting a vagrant box (using a Vagrantfile from the
 current directory) and running a fabric task on it:
 
-    import vagrant
-    from fabric.api import env, execute, task, run
-
-    @task
-    def mytask():
-        run('echo $USER')
+```python

-    v = vagrant.Vagrant()
-    v.up()
-    env.hosts = [v.user_hostname_port()]
-    env.key_filename = v.keyfile()
-    env.disable_known_hosts = True # useful for when the vagrant box ip changes.
-    execute(mytask) # run a fabric task on the vagrant host.

+v.up()
+env.hosts = [v.user_hostname_port()]
+env.key_filename = v.keyfile()
+env.disable_known_hosts = True # useful for when the vagrant box ip changes.
