(im gonna assume that you have already downloaded the game) go into the steam application then click library up on the top of the window

now that you are in your library you should see a list of games

now you want to click "Desert Bus VR" if you have trouble finding it your games are in alphabetical order so first are the games that start with "a" then "b" then "c" then "d" and here you should see the game

click play

there should be a window coming up after a little while

if you have a bad computer click settings and click all the places and put low on it

then click done and if you have a vr headset click the vr mode and if you have no vr headset click non-vr mode then the game starts

you have now completed this guide thank you
