Instructions on how to install it are included in the README.txt as well as some additional information about the mod.

If DW2 ever gets workshop support I will upload the mod to Steam of course.

Also please note that everytime DW2 updates Steam will replace the mod files with the original soundtracks again.
So after every official update you will need to replace the files again like described under "How to Install"."
