In contrast to a Help Patch, the Node Reference Page on the Wiki should contain reference material and discussions. Node Reference and Help Patch are complementary, they are not supposed to replace each other.
A good node reference page should contain

• links to external web pages describing the workings and the context of the node (eg. wikipedia, microsofts directx reference etc)
• reference material on the node´s internal workings like source code fragments, diagrams and tables
• a FAQ section
• known bugs and workarounds
• links to supplementary modules and related nodes
• changes to the semantics of the node in various releases
• a backlink section which lists all places in the wiki and in the forum, where the node is mentioned in context.
