To install manually, place the .dll file in the BepInEx/plugins folder. You need to have BepInEx installed.
Copied from the Nexus Mods page:
This mod works on singleplayer and multiplayer, I'm not sure if it works on dedicated servers. I don't know how to make the autosave time customizable, if you want a different autosave frequency message me on discord: trotyl_ and I will change it for you. If you want to improve the mod feel free to reach out on discord aswell.
