Since there is no direct reference to the Doomsday Engine in Steam Guides, at least in Ultimate Doom community guides,
I took the liberty to write a guide there, so more people on Steam get to know this great engine.
I hope you people like the idea, here is the link.
Doomsday Engine - The ultimate modern Doom experience
I plan to to the same on Final Doom, Doom II, and Master Levels, so the word gets spread.
If you feel I did something wrong or bad, or somthing needs to be revisited, please let me know.
Rep+ to this engine.
