The Documentation node () contains the end-user documentation for a physics interface node, feature node, or other builder component that needs documentation. When added by default, it uses the label User Documentation. By default, a User documentation text node appears under the main User Documentation node for Feature nodes’ documentation, for example. Right-click the main User Documentation node to add other documentation components as needed.

In the Section Heading section, you add a Heading, which is typically the name of the node that the documentation is for. The default headings, <ref entity="doc.physics"> for a physics interface and <ref entity="doc.feature"> for a feature, are references to the contents of the Description fields in those nodes’ Settings windows.

Clear the Use topic resource if available check box if you do not have a topic resource file, which would be the case for most development of physics interfaces. Then enter a description of the node under Topic description.
