+## Themes
+
+Themes can be found in ```application/views/themes```.
+
+### Creating a Theme
+
+The simplest way to create a new theme is to copy the sandbox theme folder and rename it to your desired theme name. Folder names cannot contain spaces. Once you create a new folder in the themes folder, it becomes available as a selectable theme in the admin dashboard.
+
+A theme folder should always contain these files:
+
+    _activity_feed.php //the main activity list of your theme
+    _header.php //the header of your site
+    _footer.php //the footer of your site
+    _sidebar.php //the sidebar of your site
+    home.php //the index page of your site
+    items.php //the item page of your site (search / tag results)
+    single.php //the single item view page
+    rss_feed.php //formatting for the rss feed
+    main.css //the css for your site
+
+#### Displaying Imported Items
+
+For your site's index page and item pages, an $items object is provided to the theme templates. See the _activity_feed.php file in the sandbox and boxy themes for examples on how to loop through $items and customize them based on feed they came from.
