+r"""Make it easy to install and run [browsertime](https://github.com/sitespeedio/browsertime).
+
+Browsertime is a harness for running performance tests, similar to
+Mozilla's Raptor testing framework.  Browsertime is written in Node.js
+and uses Selenium WebDriver to drive multiple browsers including
+Chrome, Chrome for Android, Firefox, and (pending the resolution of
+[Bug 1525126](https://bugzilla.mozilla.org/show_bug.cgi?id=1525126)
+and similar tickets) Firefox for Android and GeckoView-based vehicles.
+
+Right now a custom version of browsertime and the underlying
+geckodriver binary are needed to support GeckoView-based vehicles;
+this module accommodates those in-progress custom versions.
+
+To get started, run
+```
+./mach browsertime --setup [--clobber]
+```
+This will populate `tools/browsertime/node_modules`.
+
+To invoke browsertime, run
+```
+./mach browsertime [ARGS]
+```
+All arguments are passed through to browsertime.
