How to use PhpStorm to edit and debug source code on local WAMP server?

I have a local WAMP server running a project ( c:\wamp\www\myProject

). I want to edit and debug this project using PhpStorm. I thought I needed to create a project in PhpStorm and import the source code into it.

I tried using the "New Project from Existing Files ..." wizard, but I don't think I'm doing it right.

• In the wizard, I selected "Web server installed locally, source files are under its document root".
• Next page I have chosen c:\wamp\www\myProject
  
  for a directory to create a project.
• Next page I chose http://localhost
  
  for a url and named it MyProjectURL
  
  .
• The next page says, "Provide the web path of the project on your server to be added to the server root url." I left this gap because my project is right at the root. And I checked the checkbox that said "Review PHP settings" which enabled the "Next" button.
• When I click Next, the next page comes up and says "Could not detect PHP installation on server MyProjectURL
  
  " and it gives you the option to add include paths to the server.

I don't know what to do here:

• Do I need to add add paths?
• Should I just leave the checkbox unchecked to view PHP settings?
• Am I doing everything right too using this wizard?
