+Sponsorship App
+===============
+
+Sponsorship is managed via the ``sponsorship`` app.
+
+Sponsorship levels and sponsors are added via the Django admin.
+
+
+Models
+------
+
+Each sponsor level has a ``name`` (e.g. "Gold", "Silver") and an ``order``
+field which is an integer that is used to sort levels (lowest first). Each
+level also has a ``description`` which is not currently exposed anywhere
+but can be used for private annotation.
+
+Each sponsor has a ``name``, ``external_url`` (i.e. link to the sponsor's
+website), ``contact_name`` and ``contact_email``, ``logo``, and ``level``.
+
+A sponsor may also have a private ``annotation`` that can be used by
+organizers to take notes about the sponsor.
+
+A sponsor will not appear on the site until the ``active`` flag is set true.
+
+
+Template Snippets
+-----------------
+
+The easiest way to include sponsor logos, grouped by level, is to either::
+
+    {% include "sponsorship/_vertical_by_level.html" %}
+
+or::
+    
+    {% include "sponsorship/_horizontal_by_level.html" %}
+
+You can get a wall of sponsors (without level designation) with::
+
+    {% include "sponsorship/_wall.html" %}
+
+
+You can always tweak these templates or use them as the basis for your own.
+This is often all you'll need to do to display sponsors on your site.
+
+If you want to display a specific sponsor logo you can use::
+
+    {% include "sponsorship/_sponsor_link.html" with sponsor=sponsor %}
+
+or::
+    
+    {% include "sponsorship/_sponsor_link.html" with sponsor=sponsor dimensions="100x100" %}
+
+if you want different dimensions than the default 150 x 150.
+
+
+Template Tags
+-------------
+
+If you want to retrieve the sponsors and traverse them yourself, you can use
+the provided template tags::
+
+    {% load sponsorship_tags %}
+    
+    {% sponsors as all_sponsors %}
+
+or::
+
+    {% load sponsorship_tags %}
+    
+    {% sponsors "Gold" as gold_sponsors %}
+
+if you want to just get a specific level.
+
+
+You can get the levels with::
+
+    {% load sponsorship_tags %}
+    
+    {% sponsor_levels as levels %}
+
+and you can always iterate over those levels, calling ``level.sponsors`` to
+get the sponsors at that level.
