This no longer works - do not attempt to place custom content in the wrong directory and do not use Monkey Bars or Helper Monkey to install your content. Taking care of the highest quality of entertainment, we searched the Internet (because there's more than the Wicked Whims) so that your Sims 4 become a little more greasy. Since people are complex creatures in real life as well, it helps with immersion to ensure that Sims also have as many traits as possible, in order to turn them into actual complex beings.

The Packages folder will already have two files in it ( nobuildsparkles.package and nointro.package) so you'll be able to check if your mods will work.
You'll need to unzip the FrameworkSetup.zip file and place its contents into your Sims 3 directory ( Documents > Electronic Arts > The Sims 3). The Sims 3 Realistic Woohoo ModMod The Sims has a guide () that supplies you with the necessary files to create the directory.
