After the topics have been created, you need to add the footnotes to each page. The only required footnote is the Topic ID. You define the Topic ID by inserting a footnote, and using the pound sign (#) as the footnote character.
Add the Topic ID footnote:
Go to the top of the topic page and click the mouse. The footnotes must be entered at the beginning of the topic. In Word, select Insert Ø Footnote. Set the Custom Mark field to the pound sign. When you go to write the footnote text, type the Topic ID. This should be prefixed with the string “IDH_”. This helps the help compiler process the file.
