Dwemerverse is easy to install. You only need one file - the latest version.

Automatic install - Subscribe on Steam. Once subscribed, you will automatically download the latest version of the mod each time you launch the game.

Manual install - Unzip the .zip file into your Skyrim folder, so the two included files end up in the Data subdirectory of your Skyrim directory. Then just activate the mod in your Skyrim launcher and you are good to go!

Nexus Mod Manager - You can use the Nexus Mod Manager to install the mod and download new versions.
