Ways to Find/Add Immediate Prerequisites (Parent Nodes)

A node is an ancestor of another node when it contains indirect prerequisite information that a user must understand to learn the current node. For example, if node A is a parent of node B, and node B is a parent of node C, then node A is an ancestor of node C. Any parents or ancestors of node A are also ancestors of node C.
