Summary
A Steam Workshop collection is a custom compilation of mods from the official Steam Workshop. Many collections are available that function similarly to modpacks to be easily installed by users. This can make sharing mods with friends easy, as they can download an exact mod list with one button. Some game servers, such as Garry's Mod, allow users to Install Workshop Collections directly onto their server, skipping manual installation.
