Step 4: Go to where you saved the files to, and then right click them and select extract all / extract them with whatever file extracter you use (windows, and I presume Macs have a default one, which is fine for these sorts of things) Step 3: Download and save the zipped files, either from mediafire or moddb. (if you use the installer, which is largely self explanatory, you can skip to step 6)

If you're on windows you can get the installer, but I would recommend the zipped files regardless, as this will show you how most other mods for CKII are installed.
