This chapter is all about initial configuration and module setup. It does not go into detail about creating products, setting up a catalog, managing and fulfilling orders, or anything similar. For tasks like that, please refer to the specific chapters on those topics.
Feel free to skip over any topics that are not applicable to you or your store. In fact, a lot of the settings forms in Ubercart are self-explanatory, so you should use this section more as a reference than a tutorial for getting started.
