Place the downloaded file directly into the Mods folder. You can organize mods into subfolders up to one level deep.
Launch The Sims 4 and go to Game Options > Other. Make sure "Enable Custom Content and Mods" is checked.
Restart the game if it was already running. The mod should now appear in your game.
