Customize Online Help Files White Paper
This white paper walks through how to add custom HTML pages to the online help files, both in the web help and CHM file formats. Note that it is strongly recommended that you first back up all installed help files before beginning. Also, when replacing installed help files with custom help files, you MUST retain the same path and file names to ensure all links to the online help continue to work properly. This applies to both web help and CHM files.
