+# Prolog-less submit rules, easy and for everyone
+
+For many teams it is important to customize the conditions that make a change
+submittable (e.g. to enforce non-author code reviews). The traditional way to do
+this is via
+[Prolog submit rules](https://gerrit-review.googlesource.com/Documentation/prolog-cookbook.html#SubmitRule),
+but many project owners struggle with Prolog and find Prolog submit rules hard
+to use. Writing, testing and maintaining complex Prolog rules can be difficult
+and time-consuming. In this talk I want to introduce you to an alternative and
+show you how submit rules can be easily configured from the WebUI by using the
+[simple-submit-rules plugin](https://gerrit-review.googlesource.com/admin/repos/plugins/simple-submit-rules).
+The plugin is based on a
+[new extension point](https://gerrit-review.googlesource.com/admin/repos/plugins/simple-submit-rules)
+that allows to implement submit rules in Java. I will explain how you can use
+this extension point to add your own submit rules and how submit rules from
+different plugins can be combined.
