Title: How to work with HTML Help (.chm) files
(Delphi offers a comfortable way to show context sensitive helpfiles,
however the support is limited to the Windows help system (.hlp). If
you want to work with HTML help files (.chm), then you have to write
some extra code. Following this link you can find a unit, which will
allow you to use HTML help files.

You can use the normal Delphi VCL framework and write your projects
the same way, as you would using normal (.hlp) files. Simply add the
unit to your project.
