+This is a tool that calculates the
+[Template Influence Factor](https://en.wikipedia.org/wiki/User:The_Earwig/Sandbox/TIF)
+of a [Wikipedia template](https://en.wikipedia.org/wiki/Help:Template), which
+is a measure of how
+[high risk](https://en.wikipedia.org/wiki/Wikipedia:High-risk_templates) it is,
+for the purposes of anti-vandalism. It runs on
+[Wikimedia Labs](https://tools.wmflabs.org/earwig-dev/tif).
+
+Dependencies
+============
+
+* [earwigbot](https://github.com/earwig/earwigbot) >= 0.2
+* [flask](http://flask.pocoo.org/) >= 0.10.1
+* [flask-mako](https://pythonhosted.org/Flask-Mako/) >= 0.3
+* [mako](http://www.makotemplates.org/) >= 1.0.3
+* [oursql](http://packages.python.org/oursql/) >= 0.9.3.1
+
+Running
+=======
+
+- Install all dependencies listed above.
+
+- Create an SQL database ...
+
+- Create an earwigbot instance in `.earwigbot` (run `earwigbot .earwigbot`). In
+  `.earwigbot/config.yml`, fill out the connection info for the database by
+  adding the following to the `wiki` section:
+
+        _tifSQL:
+            host: <hostname of database server>
+            db:   <name of database>
+
+  If additional arguments are needed by `oursql.connect()`, like usernames or
+  passwords, they should be added to the `_tifSQL` section.
+
+- Start the web server (on Tool Labs, `webservice2 uwsgi-python start`).
