Setting up Test Admiral and Test Swarm for running nightwatch javascript tests

I am following this TestArmada link http://ift.tt/2nLQLFk to set up Test Admiral and Test Swarm to run my javascript tests. I am new to Apache and facing issues setting up Apache for Test Admiral.

In the TestArmada link above in steps>step #3 - it says: "To run Admiral from a non-root directory, set web.contextpath in localSettings.json to the correct path from the web root and update RewriteBase in .htaccess. Verify that .htaccess is working properly by opening a page other than the HomePage (e.g. /testswarm/projects) in your browser."

In locaSetting.json Do I need to set up web.contextpath with "Library/WebServer/Documents"?

I have the repo from above TestArmada link under Users/sunil/myproject/testadmiral/.

I have started Apache on my mac and typing localhost in browser says "It works".
