-    First, create the stream you'd like to use for notifications, and subscribe
-    all interested parties to this stream. We recommend the name <code>travis</code>.
-</p>
-
-<p>
-    Next, set up a bot for the integration. You'll need the bot's API key
-    to construct a URL for Travis CI.
-</p>
-
-
-<p>
-    Finally, set up a webhook in your <code>.travis.yml</code> file:
-</p>
-
-<pre>
-notifications:
-webhooks:
-- {{ external_api_uri_subdomain }}/v1/external/travis?stream=travis&amp;topic=build-status&amp;api_key=abcdefgh
-</pre>
-
-<p>
-    By default, pull request events are ignored since most people
-    don't want notifications for new pushes to pull requests.  To
-    enable notifications for pull request builds, just
-    add<code>&ignore_pull_requests=false</code> at the end of the url.
-</p>
-
-<p><b>
-    Congratulations! You're done!</b><br/> When a code build occurs,
-    you're receive a notification on the specified stream and topic.
