How do I add a book to my site? I installed this plugin and can not understand how you can add a book, help please. Sorry for my bad english

Hello,

If you have free version, you may add books only from backend.

if you have pro version, you s customers may add books from frontend(if you permit that), Please check menu "My Book" and button "Add book" - what you see at all category view.

For add Book Library show to site frontend - you need create menu to Book library in Joomla menu manager

Please check ours Book library tutorials http://ordasoft.com/Table/Joomla-Tutorials/
