Confused about section 2.F. Conflicting Graphics. Install just one or all?

[Component_Actual]

I am trying to follow the STEP Core Guide completely, and have installed everything up to section 2.F. Conflicting Graphics. I am confused about the meaning of this section title. Are we only suppose to select one of the mods from this section because otherwise they will conflict with one another, or are we suppose to install all of these mods from this section? Is there anything special we need to do to make these mods work besides following the detailed intructions and creating a bashed patch?

No, what it means is that they are large texture packs that overwrite a lot of other textures especially from the vanilla game but they also have overwrite between other mods in that particular section. You install all of them for STEP: Extended and only the ones with Green next to their names for STEP: Core

Thanks, I was like 80% sure that is what it meant, but I have been about 80% sure of what to do about 80 times thus far, and if I don't ask stupid questions I will eventually end up doing something stupid.
