Open your Steam folder and navigate to steamapps\common\dota 2 beta\game\dota. Download and extract intaller archive (alternative link) here (archive files into this location).

Paste your mods files into folder called “files” (it can be found here) – models, sounds, particles and other subfolders need to be inside this folder.

Run “Install Mods.exe” (location), wait a little bit until it is complete and press Enter (you might need to rerun this program after updates).

Do not use additional console commands (remove -addon dotamods if you have it from launch options).
