You didn't mention nothing about your OS. For Windows you can take a look at this thread: http://blender.org/modules.php?op=modload&name=phpBB2&file=viewtopic&t=5119&sid=d9e2127167a2f7b307e40ede5a9f8f0a This is my way to do it. Can't convert doc's to PDF here but I'll investigate this later. For now CHM is fine for me.
