NP. If you ever want to try again later, i've taken a screenshot of the layout needed.
Right click 7 days to die in your steam library, hit properties, then click the tab titled "Local Files". Click on Browse Game Files. This will open up the folder in the center of the screenshot. If you do not have a Mods folder, create one. Be sure to capitalize the M. Once that's done, open the Mods folder and drag the unzipped file from the download into the Mods folder. Boom, you're done.

For the server, it's the exact same thing. Just depends on how your server provider gets to the files... The screenshot i took was through an FTP server.
