+## Kibana Testbed
+
+Sometimes when developing for Kibana, it is useful to have an isolated routable space to demonstrate new functionality. This Testbed provides such a space.
+
+To make use of the testbed, edit the testbed.js, testbed.html, and testbed.less files as necessary. When you are done demonstrating
+your new functionality, remember to cleanup your changes and restore the testbed to its pristine state for the next person.
+
+To access the testbed, visit `http://localhost:5601/app/kibana#/testbed`
