+Dynamic Django settings in Redis.
+
+Features
+========
+
+* Easy migrate your static settings to dynamic settings.
+* Admin interface to edit the dynamic settings.
+
+Installation
+============
+
+Install from here using ``pip``::
+
+    pip install -e hg+http://bitbucket.org/comoga/django-constance#egg=django-constance
+
+1. Add ``constance`` to your ``INSTALLED_APPS``.
+
+2. Point ``CONSTANCE_CONNECTION`` in your ``settings.py`` to your Redis instance, like this::
+
+        CONSTANCE_CONNECTION = {
+            'host': 'localhost',
+            'port': 6379,
+            'db': 0,
+        }
+
+3. Create an empty section ``CONSTANCE_CONFIG`` in your settings which will
+   enumerate all your dynamic settings for the admin::
+
+        CONSTANCE_CONFIG = {
+        }
+
+Usage
+=====
+
+Add
+
+::
+
+    from constance import config
+
+to the top of your source and replace ``settings.MY_SETTINGS_KEY`` with
+``config.MY_SETTINGS_KEY`` for each key which you want to be read
+from Redis.
+
+Next, move each such key within your ``settings.py`` to the ``CONSTANCE_CONFIG``
+section. Keep the default value and add an explanation for the admin, like
+this::
+
+    CONSTANCE_CONFIG = {
+        'MY_SETTINGS_KEY': (42, 'the answer to everything'),
+    }
+
+
+Fire up your ``admin`` and you should see a new application ``Constance``
+with ``MY_SETTINGS_KEY`` in the ``Config`` pseudo model.
