The proper way to install

What's the proper way for me to download all the packs and install them into the graphics folder? Could someone take an SS of what their graphics folder looks like and give a little step by step guide? Thank you!

OT question: I download 13 parts to a cut of face megapack and I placed all the photos inside into ONE "faces" folder, is that correct or should I have added each faces folder individually so there would of been 13 faces folders in the graphics folder? I say this as I've noticed my game is substantially slower when playing.

Thanks!

Also what's the significance of the config file? say if I want to add the Liga adelante to the spain clubs file, should I replace the config file? Also what does it do?

Additionally, are there competition ESS logos? I.E Champions League, World Cup etc?
