Sideloading refers to the process of installing third-party mods, maps, and avatars that aren't available through the official in-game repository

• Open the archive and confirm files are what you expect: assets, .dll, .json, or .cfg files.

• Enjoy tinkering (you don’t mind dragging files into folders)

• Own a Quest 3 (extra RAM makes mods much more stable)
• Already have a PC for downloading mods (you can do it via Android + USB-C, but it’s tedious)
