-Generic library for generating "booster packs" with randomizable slots for foils and special rares.
+Generic library for generating "booster packs" and drafting them in pods.
+
+Booster packs allow for randomizable slots for foils and special rares.
 
 The base library has generalized implementations of sets (think booster packs from boxes) and cube (which takes off cards from a list as they are put in packs).
