How to install + serve Tildes directly on a VPS?

Hi,

I would like to run a Tildes instance on a VPS, using a custom domain.

QUESTION:

Is it possible to install and serve Tildes directly on a VPS? (eliminate Vagrant / VirtualBox entirely)

Being a solo dev, it feels like Vagrant / VB adds excess complexity for little benefit.

• note 1: I tried the Vagrant / VB install method (on an Ubuntu VPS), and hit some errors - all related to Vagrant / VB.

• note 2: I found this 3-year old comment of Deimos’ instructions, though I'm guessing it's out of date, since the code has changed a lot in 3 years (salts, minions, etc).

If it IS possible to install and serve Tildes directly on a VPS - what is the best / simplest way to do it in 2022?

I will very much appreciate any ideas.
