 Images

 The next step is probably to install a docker image, for this we have a
 defined type which can be used like so:
 
-   .. code-block:: ruby
+.. code-block:: ruby
 
-      docker::image { 'base': }
+  docker::image { 'base': }
 
 This is equivalent to running:
 
-   .. code-block:: bash
+.. code-block:: bash
 
-      docker pull base
+  docker pull base
 
 Note that it will only if the image of that name does not already exist.
 This is downloading a large binary so on first run can take a while.
 For that reason this define turns off the default 5 minute timeout
 for exec. Note that you can also remove images you no longer need with:
