How to install talkyard locally on windows device?

You can use Vagrant: https://www.vagrantup.com/downloads.html

Download this file and follow these instructions therein: https://github.com/debiki/talkyard-prod-one/blob/master/scripts/Vagrantfile

(This should work — Vagrant is cross platform, Windows too.)

B.t.w. I suggest you change from vb.memory = "2000" to 4000, in the Vagrantfile.

Talkyard will listen on your localhost:8080, once you're done.
