+<%#
+# Index
+
+This view is the template for the index page.
+It is responsible for rendering the search bar, header and pagination.
+It renders the `_table` partial to display details about the resources.
+
+## Local variables:
+
+- `page`:
+  An instance of [Administrate::Page::Collection][1].
+  Contains helper methods to help display a table,
+  and knows which attributes should be displayed in the resource's table.
+- `resources`:
+  An instance of `ActiveRecord::Relation` containing the resources
+  that match the user's search criteria.
+  By default, these resources are passed to the table partial to be displayed.
+- `search_term`:
+  A string containing the term the user has searched for, if any.
+- `show_search_bar`:
+  A boolean that determines if the search bar should be shown.
