+deform_mako
+===========
+
+This is a Mako port of the Chameleon templates included in Deform.
+
+To run the `deformdemo <http://deformdemo.repoze.org>`_ application using the
+``deform_mako`` renderer:
+
+- Create a virtualenv::
+
+    $ virtualenv2.6 --no-site-packages env
+
+  Heretofore, the ``env`` directory created above will be referred to as
+  $VENV
+
+- Clone the deformdemo GitHub repository::
+
+    $ git clone git://github.com/Pylons/deformdemo.git
+
+- cd to the deformdemo checkout and ``setup.py develop`` it into your
+  virtualenv
+
+    $ cd deformdemo
+    $ $VENV/bin/python setup.py develop
+
+- Use the deform_mako ``demo.ini`` file to run a demo app server via ``paster
+  serve``:
+
+    $ $VENV/bin/paster demo.ini
+
+- The demo app will be running on port 8521.  See the ``README.rst`` in the
+  deformdemo checkout for instructions about how to run the selenium tests.
