 Just go with something like:
 
-    javascripts:
-      public:
-        vendor: 'undescore,modernizr'
-        public: '**/*'
-    stylesheets:
-      public:
-        - 'reset,shared,base,home'
+```yml
+javascripts:
+  public:
+    vendor: 'undescore,modernizr'
+    public: '**/*'
+stylesheets:
+  public:
+    - 'reset,shared,base,home'
+```
 
 Then if you have the following directory structure:
 
-    javascripts
-      - vendor
-        - underscore.js
-        - modernizr.js
-      - public
-        - main.js
-        - fallback.js
-    stylesheets
-      - reset.css
-      - shared.css
-      - base.css
-      - home.css
+```
+javascripts
+  - vendor
+    - underscore.js
+    - modernizr.js
+  - public
+    - main.js
+    - fallback.js
+stylesheets
+  - reset.css
+  - shared.css
+  - base.css
+  - home.css
+```
 
 then running the following code will give you the files you need:
 
-    > expander.processGroup('stylesheets', 'public')
-    > ['stylesheets/reset.css', 'stylesheets/shared.css', 'stylesheets/base.css', 'stylesheets/home.css']
+```
+> expander.processGroup('stylesheets', 'public')
+> ['stylesheets/reset.css', 'stylesheets/shared.css', 'stylesheets/base.css', 'stylesheets/home.css']
 
-    > expander.processGroup('javascripts', 'public')
-    > ['javascripts/vendor/underscore.js', 'javascripts/vendor/modernizr.js', 'javascripts/public/main.js', 'javascripts/public/fallback.js']
+> expander.processGroup('javascripts', 'public')
+> ['javascripts/vendor/underscore.js', 'javascripts/vendor/modernizr.js', 'javascripts/public/main.js', 'javascripts/public/fallback.js']
+```
