+The configuration that you'll need to do is minimal. The first piece of development work is to define a model and form for your attendee profile, and the second is to implement a payment app.
+
+
+Installing Registrasion
+-----------------------
+
+Registrasion depends on an in-development version of Symposion. You'll need to add the following two lines to your ``requirements.txt`` files::
+
+    git+https://github.com/pinax/symposion.git@ad81810
+    git+https://github.com/chrisjrn/registrasion.git@releases/0.1
+
+Symposion currently specifies Django version 1.9.2.
+
+Running ``pip install -r requirements.txt`` will pull down the git version of Symposion as well as the current 0.1 release of Registrasion.
+
+
+Configuring your Django App
+---------------------------
+
+In your Django ``settings.py`` file, you'll need to add the following to your ``INSTALLED_APPS``::
+
+  "registrasion",
+  "nested_admin",
+
+You will also need to configure ``symposion`` appropriately.

 The inventory model is split up into Categories and Products. Categories are used to group Products.
 
 Registrasion uses conditionals to build up complex tickets, or enable/disable specific items to specific users:
