 What formats does |app| read metadata from?

 Where are the book files stored?
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-|app| use a database to store all books. When you import new books or convert an existing book, the book files are stored in compressed form in the database. The database is a single file named `library1.db` and you can see where it is (or change its location) by clicking the configuration button (the button with the icon of a hammer next to the search bar). 
+When you first run |app|, it will ask you for a folder in which to store your books. Whenever you add a book to |app|, it will copy the book into that folder. Books in the folder are nicely arranged into sub-folders by Author and Title. Metadata about the books is stored in the file ``metadata.db`` (which is a sqlite database).
 
-Can I save my books to the disk?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-You can save your books to the disk by selecting the books and clicking the "Save to disk" button. Your books will be saved in nicely organized folders.
