Installing kirby 3

Hi have Kirby 2 installed on Windows xampp localhost.
Like to upgrade to Kirby 3 - not upgrading any sites, once I’ve installed / upgraded to Kirby 3 I’ll create the new site.
Just like a pointer to how to install kirby 3.

Thanks for any help

There are different ways to install Kirby 3, the simplest is to download the Starterkit or the Plainkit and put the unzipped folder into your public html folder (whatever that is called on windows Xampp, probably /htdocs);

Other options:

Installation with git:
Installation with composer:

If this doesn’t help, please be more specific what exactly is not working as expected.
