To make a modpack, you first need to know how to install mods. Use Google or search the official forums. Once you've done that, you just add the mods you want. If yuor using some of the Technic modpacks, you might find two .jars in the bin folder, you would want to add mods the the one titled "modpack" Hope this was helpful and not utterly confuzzling.

I'd just like to say that Frizzil is still working on this mod, and frequently posts in his thread of the minecraft forums.
