Looks capable, but no documentation

Looks like it will meet all my requirements for managing a small library, but I really wish there was some kind of documentation to walk through the various ways of adding books (specifically bulk adds), customizing, etc. Documentation is provided for installing the plugin, but it installs just like any other plugin. The forum seems to be abandoned in place…8 posts, no replies from anyone.
Decent documentation would take it to 5 stars.
