@mbround18 Apologies if the answer to this is obvious but I was still a little confused even after reading the updated documentation in this PR. Is it expected that to enable BepInEx we manually install it from the container after launching it?

@paulmoore yes, there are so many versions of BepInEx, Doorstop, and other mods floating around that it would be impossible for me to track down a reliable version for installation. Since modding is in its infancy for Valheim right now, you will have to manually install BepInEx, Doorstop, and the reconstructed libraries that Valheim uses. Ill have a guide up in a little bit about how to install BepInEx inside the container using ValheimPlus as an example mod.

Another big one which is gaining traction is InSlimVML which I might have to build a custom launcher for but I am waiting until I can test locally with it.
