The sample nodes provided with the product demonstrate this feature.
For further explanation of extension points and how to use them, see the PDE Guide.
When a node is created, a HelpContexts.xml file is created. This assigns a context id based on the name of the node. You can modify the HelpContexts.xml file for your node by changing the text on the description field. The name of the HelpContexts.xml file must be unique within the project but can contain multiple context entries, for example, if you had several nodes within a single project, each node can have its context-sensitive help in the file.

If you do not want to add any of the optional features, you can test your node at this point. To do this you need to launch another instance of the workbench, and select Run > Run as > Runtime Workbench. See the PDE Guide for more information about testing using the Runtime Workbench.
