Skinning Guide?

[SaintDog]

Creating a style (skin) for vBulletin isn't as easy as simply uploading images and then you're done, you'll still need to work with the templates to achieve the effect you're after.

The complexity depends on how complex your current style/skin already is. Most work is done through the header and footer templates within vBulletin, though many go deeper into the additional templates vBulletin has.
