Description

This field can be used to describe or summarize the current topic. It is used by the default HTML template to generate the HTML description tag for better Search Engine Optimization (SEO).


Help ID

This is one of the most important part of a topic when using the generated documentation. The help ID is a unique alpha-numeric identifier used to locate the topic. This ID will be used to name individual HTML files in the generated HTML documentation, and can be used to open that specific topics from any programming language in the CHM documentation.

Note: If the "Always synchronize Help ID with topic caption" project option is checked, HelpNDoc will automatically replace a custom Help ID when the topic's caption is changed.


Note: The Help ID can only contain alpha-numeric and "-" characters. HelpNDoc will ensure this rule by automatically removing any unwanted characters (such as spaces) from the input.
