 Alternatively, you may build the Fuel .iso from source by cloning the
 opnfv/fuel git repository.  To retrieve the repository for the Colorado release use the following command:
 
-$ git clone https://gerrit.opnfv.org/gerrit/fuel
+.. code-block:: bash
+
+    $ git clone https://gerrit.opnfv.org/gerrit/fuel
 
 Check-out the Colorado release tag to set the HEAD to the
 baseline required to replicate the Colorado release:
 
-$ git checkout colorado.1.0
+.. code-block:: bash
+
+    $ git checkout colorado.1.0
 
 Go to the fuel directory and build the .iso:
 
-$ cd fuel/build; make all
+.. code-block:: bash
+
+    $ cd fuel/build; make all
