The doc "For the 1st Time" is wrong. I am trying to set up a project and the instructions reference "Root URL", "Remote Root Directy", etc. and these parameters don't exist in the Project dialog!

Also, I already have a PHP project (non-PhpED) that I have been working on...in another folder. There are no instructions as to how I am supposed to work with a project that is somewhere else on my disk.

Could you please explain in details what you're talking about?

Take a look at the PhpED project dialog screenshot below and it for sure contains the termins you were looking for:

My mistake. I didn't see the "Run Mode" dropdown. "System Default" doesn't show the options mentioned.

Sorry.

Right, they are grayed out if SRV mode is selected. But they are still there
