+
+When passed one or more resource types those resources are rendered through templates. The templates are loaded based on a template matching the exact resource type name with a .jinja2 extension or an optionally passed template.
+
+.. code-block:: bash
+
+   $ python puppetdb-stencil.py mytype
+
+A more complex example that renders multiple types through a shared template:
+
+.. code-block:: bash
+
+   $ python puppetdb-stencil.py nagios_host nagios_hostgroup -t examples/nagios_.jinja2
+
+Template selection
+------------------
+
+The jinja2 loader is used to first search in the current directory and then the absolute path. This is done for every template specified. A template name is generated for the current resource type name.
+
+.. code-block:: bash
+
+   $ python puppetdb-stencil.py nagios_host -t examples/nagios_.jinja2
+
+This looks in these places:
+
+* ``nagios_host.jinja2``
+* ``/nagios_host.jinja2``
+* ``examples/nagios_.jinja2``
+* ``/examples/nagios_.jinja2``
+
+Installation
+------------
+
+This project requires pypuppetdb and Jinja2 to function. On Python 2.6 it additionally requires argparse.
+
+.. code-block:: bash
+
+   $ pip install -r requirements.txt
