+GitHub
+------
+
+Github webhook events can be configured as triggers.
+
+A connection name with the github driver can take multiple events with the
+following options.
+
+  **event**
+  The event from github. Supported events are ``pull_request``,
+  ``pull_request_review``,  and ``push``.
+
+  A ``pull_request`` event will
+  have associated action(s) to trigger from. The supported actions are:
+
+    *opened* - pull request opened
+
+    *changed* - pull request synchronized
+
+    *closed* - pull request closed
+
+    *reopened* - pull request reopened
+
+    *comment* - comment added on pull request
+
+    *labeled* - label added on pull request
+
+    *unlabeled* - label removed from pull request
+
+    *review* - review added on pull request
+
+    *push* - head reference updated (pushed to branch)
+
+  A ``pull_request_review`` event will
+  have associated action(s) to trigger from. The supported actions are:
+
+    *submitted* - pull request review added
+
+    *dismissed* - pull request review removed
+
+  **branch**
+  The branch associated with the event. Example: ``master``.  This
+  field is treated as a regular expression, and multiple branches may
+  be listed. Used for ``pull_request`` and ``pull_request_review`` events.
+
+  **comment**
+  This is only used for ``pull_request`` ``comment`` actions.  It accepts a
+  list of regexes that are searched for in the comment string. If any of these
+  regexes matches a portion of the comment string the trigger is matched.
+  ``comment: retrigger`` will match when comments containing 'retrigger'
+  somewhere in the comment text are added to a pull request.
+
+  **label**
+  This is only used for ``labeled`` and ``unlabeled`` ``pull_request`` actions.
+  It accepts a list of strings each of which matches the label name in the
+  event literally.  ``label: recheck`` will match a ``labeled`` action when
+  pull request is labeled with a ``recheck`` label. ``label: 'do not test'``
+  will match a ``unlabeled`` action when a label with name ``do not test`` is
+  removed from the pull request.
+
+  **state**
+  This is only used for ``pull_request_review`` events.  It accepts a list of
+  strings each of which is matched to the review state, which can be one of
+  ``approved``, ``comment``, or ``request_changes``.
+
+  **ref**
+  This is only used for ``push`` events. This field is treated as a regular
+  expression and multiple refs may be listed. Github always sends full ref
+  name, eg. ``refs/tags/bar`` and this string is matched against the regexp.
+
+GitHub Configuration
+~~~~~~~~~~~~~~~~~~~~
+
+Configure GitHub `webhook events
+<https://developer.github.com/webhooks/creating/>`_.
+
+Set *Payload URL* to
+``http://<zuul-hostname>/connection/<connection-name>/payload``.
+
+Set *Content Type* to ``application/json``.
+
+Select *Events* you are interested in. See above for the supported events.
