-**Testing Out Protractor Interactively**
-
-When debugging or first writing test suites, you may find it helpful to
-try out Protractor commands without starting up the entire test suite. You can
-do this with the element explorer.
-
-To run element explorer, simply run protractor as you normally would, but pass in
-the flag --elementExplorer:
-
-    protractor --elementExplorer
-
-This will load up the URL on WebDriver and put the terminal into a REPL loop.
-You will see a > prompt. The `browser`, `element` and `protractor` variables will
-be available. Enter a command such as:
-
-    > browser.get('http://www.angularjs.org')
-
-or
-
-    > element(by.id('foobar')).getText()
-
-Typing tab at a blank prompt will fill in a suggestion for finding
-elements. You can also use the `list(locator)` command to list all elements
-matching a locator.
-
-Element explorer will start chrome by default. However, you can specify
-another browser, change browser settings, or specify any other config that you
-normally would with your protractor test. To do this, pass configs to
-protractor like you normally would,
-but with the `--elementExplorer` flag set:
-
-    protractor [configFile] [options] --elementExplorer
-
-For example, to connect to ChromeDriver directly, use
-
-    protractor --directConnect --elementExplorer
-
-Element explore will ignore your specs, not set up your framework (e.g. jasmine,
-mocha, cucumber), and only allow you to pass in 1 capability, but will honor
-every other parameter in your config.
-
-Note `baseUrl` is used here as the initial page, i.e. element explorer will try
-to navigate to `baseUrl` automatically on start.
