Restart The Sims 4 - you will need to do this so that your new mods are launched along with the game. Drag all of your extracted files from this mod into your mod folder.
Navigate to your documents folder in a new window, click on ‘Electronic Arts’, then ‘The Sims 4’, then ‘Mods’, which should showcase a folder with all of your mods in it.
Open your Downloads folder and unzip your mod, by left-clicking it and selecting ‘Extract’. Make sure your mods are ones that people are using and talking about (like the ones we’ve suggested below), so you don’t download anything that might be harmful. You can find mods from The Sims Resource and various smaller creator’s websites as well. Download a mod of your choice into your Downloads folder.
