 If you want to run Appium via an `npm install`, hack with or contribute to Appium, you will need
 [node.js and npm](http://nodejs.org) 0.8 or greater (`brew install node`).
 
+To verify that all of Appium's dependencies are met you can use `appium-doctor`.
+Run `appium-doctor` and supply the `--ios` or `--android` flags to verify that all
