Once you are done with your music kit, you will need to submit it.
Create a ZIP archive of your music kit that has the following directory layout.
- *.mp3 files
- Your .wzproj.txt file.
You can find the .wzproj.txt file by going here <Steam Install>\steamapps\common\GarrysMod\garrysmod\data\warzone\workbench and looking for the project file you created for the music kit.
Submit your entry in this forum: https://warzone.gg/forum/index.php?/forum/49-music-kit-submissions/ but do not include the ZIP file, keep this on your PC, you will be asked to send it privately if your submission is accepted.
