This isn't unusual with software today. Gone are the days with bookshelves of user manuals, and locally based support. My tech bookshelves have far fewer user manuals than there are my backups of install disks than even from a few years ago. There are fewer software boxes too, with the storage and networks we have today.
Why should any company spend the money creating a library when the information can be better searched online. Even the big, expensive, and I mean far more expensive software packages than this, no longer have a user manual or manuals to speak of. Installing something today is nothing more than a download or cloud connection, and with that comes maybe a brief how to document online, or if it is a disc it comes with a two-pager quick-start guide and the rest of the information is available off the company website in a wiki. Again why waste resources, especially with a small company with limited resources, which can be put to better use elsewhere.
