Go to https://store.steampowered.com/about/ and “Install Steam”.
From your Steam client, click on “Store”, then search for “Tabletop Simulator” and buy it. (If you have three friends who also want a copy, it’s cheaper to buy a 4-pack; you can’t do this if you already own it. It’s on special offer, around half price, three or four times a year.) Download and install.
It’s worth doing the in-game tutorial to get the hang of how things work.
From your Steam client, go to Games and Tabletop Simulator. Scroll down to “Explore the Workshop”, and search for Dwarf; or go directly to https://steamcommunity.com/sharedfiles/filedetails/?id=1709437929. Select “Subscribe” and the Dwarf mod will be downloaded to your local copy of Tabletop Simulator.
Run Tabletop Simulator, and select Create (either a single player game or a server for other people to join you); then within the main client select Games, Workshop, Dwarf. Shuffle each deck of cards (mouse over it and tap “R”) before you start playing.
