How to install

Most of the time when possible I give you the possibility to install as either Sims3Pack or Package.
Pick up a format you rather use (poses can only be installed as Packages), and install it in your game:

If you use EA Launcher:

Sims3Packs
Place the .sims3pack file in your folder My Documents/Electronic Arts/The Sims 3/Downloads
Run the Launcher, click the Download panel on the left and select the files you want to install before pressing the Install button.
Note: You do not need to keep the file in this folder, it can be removed safely once installed and the Launcher/game is closed.

Packages
Place the .package file in your folder My Documents/Electronic Arts/The Sims 3/Mods/Packages
If you do not have or do not know how to set up the Mods folder, I wrote a tutorial here.
Note: If you have too many files in this folder you should consider merging them or it will make your game load and render slower. Aikea Guinea wrote a tutorial about it, see here.

If you use CC Magic:

This launcher manages both types, so you can place any .sims3pack and .package files you want in
My Documents/Electronic Arts/The Sims 3/Downloads
For those who don't know about it, you can find the installation here and a tutorial there.
