Okay I have not been able to get Kirby (Plainkit download) to work using Terminal as per the Getting Started video (Quickstart | Kirby CMS) on a local server on my Mac.
So I have downloaded a free trial of something called MAMP (as per suggestion here https://getkirby.com/docs/cookbook/setup/development-environment).
I’ve opened the MAMP app. Now what do I do?
