+# Design of DocMan
+
+There are two kinds of tabs: library tab and viewer tab.
+
+The book library is a split view: on the left, the list of books in
+the library; on the right, the metadata of the currently selected
+book, which has editable fields.
+
+How does the library work? It's just a folder, no database, no
+nothing. The way the folder is organized is completely up to the
+user. It could just be a mashup of PDFs and EPUBs, completely without
+any subfolders. The software organizes those files into a neat view.
+
+Second, the document viewer. It's something vastly more optimized than
+the GNOME bloatware, something that uses perhaps Poppler, like
+qpdfview which is absurdly fast. The document viewer can annotate,
+make bookmarks, etc. None or several tabs of the viewer can be opened
+at once.
+
+DocMan should be like the DeaDBeeF or Foobar2000 but for books.
