Open your apps menu, press “All” in the top right corner and scroll down to unknown sources.
Then select unknown sources and launch BMBF
In the BMBF app, they will give you steps on what to do next.

Once you have completed the steps given to you by BMBF, open the browser in BMBF and go to the BSMG discord.

There, you can find archives of Beat Saber mods for both Quest and PC of multiple Beat Saber versions.

There, you can install Beat Saber mods onto your Quest.
