-### Under the hood

+Configure everything in your app with a `.persistent_selenium` file:
+
+``` ruby
+# .persistent_selenium
+PersistentSelenium.configure do |c|
+  c.browser = :chrome
+  c.chrome_extensions = %w{AngularJS-Batarang.crx}
+end
+```
+
+### Chrome Extensions
+
+If, for example, you do a lot with AngularJS and want to use [Batarang](https://chrome.google.com/webstore/detail/angularjs-batarang/ighdmehidhipcmcojjgiloacoafjmpfk?hl=en),
+download the extension, put it in your project's folder somewhere, and call `persistent_selenium` with the path
+to the extension:
+
+``` bash
+persistent_selenium --browser chrome --chrome-extensions AngularJS-Batarang.crx
+```
+
+## Best practice
+
+Use it with Foreman and Guard. Start up your test suite via Guard, configure your test suite to
+use persistent_selenium, and run persistent_selenium alongside it:
+
+``` yaml
+guard: guard -g wip
+ps: persistent_selenium
+```

 You're most likely using `all` and invoking an action on one of the nodes within, I'd wager. If you need to find a node
 to perform an action on, it's best to stick with `find`, since it's less likely that node will go out of
