# Loading Campaign Materials

The first thing the user will need to do once PCGen has been launched is to load a set of source material data sets. PCGen provides an extensive library of data sets from a broad range of RPG publishers. Loading these sets can be accoplished in one of two methods:

Basic Mode provides a selection of the more commonly used data sets as preconfigured collections ready for loading. This mode also allows the user to add their own preconfigured set through the creation of a custom PCC file.

Advanced Mode allows the experienced user access to the complete list of available data sets and provides complete control over which sets are loaded.
