Does VSdocman work with VS 2010/2008/2005 Express editions?
No. The Express editions of Visual Studio 2005/2008/2010 don't support add-ins, macros and packages. You need to have VS Standard edition or higher to run VSdocman or any other add-in.
You can add your own custom topics. Using WYSIWYG editor, you can create any number of custom topics such as overview, examples, license agreement, usage descriptions, etc. You can define your own structure of table of contents (TOC) with topics and chapters. You can place generated API documentation anywhere in the TOC. You can even split API reference and insert specified namespaces at various places.
