+Pulpito
+=======
+
+This role is used to configure a node to run pulpito_.
+
+It has been tested on:
+
+- CentOS 7.x
+- Debian 8.x (Jessie)
+- Ubuntu 14.04 (Trusty)
+
+Dependencies
+++++++++++++
+
+Since pulpito_ is only useful as a frontend to paddles_, it requires a paddles_ instance to function. Additonally, you must set ``paddles_address`` in e.g. your secrets repository to the URL of your instance.
