+ *
+ * This command helps you to debug your integration tests. It stops the running browser and gives
+ * you time to jump into it and check the state of your application (e.g. using the dev tools).
+ * Your terminal transforms into a [REPL](https://en.wikipedia.org/wiki/Read%E2%80%93eval%E2%80%93print_loop)
+ * interface that will allow you to try out certain commands, find elements and test actions on
+ * them.
+ *
+ * [![WebdriverIO REPL](http://webdriver.io/images/repl.gif)](http://webdriver.io/images/repl.gif)
+ *
+ * If you run the WDIO testrunner make sure you increase the timeout property of your test framework
+ * your are using (e.g. Mocha or Jasmine) in order to prevent the continuation due to a test timeout.
+ * Also avoid to execute the command with multiple capabilities running at the same time.
