======================
For MS-DOS (DOOM2.WAD)
======================

You will see that the launcher used to select maps have a new option made to set your weapons. You can also access this menu typing WEAPONS.BAT

If you use another executable that isn't the one included on MS-DOS EDITION you may have to apply the Dehacked files manually;
 
================================================
For any port that isn't ZDoom-based or Eternity:
================================================

You need to use command lines or a launcher like ZDL. Just choose any DEH weapon you want to replace and add them at the end of the line - for example: 
crispy-doom -file SCYTHE.WAD D4V.WAD FSCYTHE.WAD -nodeh -deh D4V.deh 2_MARKV.deh 3_REAPER.deh 7_GAUSS.deh 

** The -nodeh parameter after D4V.WAD is very important, don't forget it **

You can also open the bat files included here to add your weapons.

================================================
For ZDOOM-based ports (GZDoom, ZDoom, Zandronum)
================================================

DON'T LOAD the additional DEHs files.
Just run the mod as normal and go to the options menu.

You will see a new option called "D4V - WEAPON SETUP" where you can select your weapon.

===============
Eternity Engine
===============

On Eternity you will have to remove the DEHACKED lump on D4V.WAD using a program like Slade. 

The Vortex Rifle will not work here, unfortunately.
