+# Tutorial: DevShelf
+
+DevShelf is a **digital library search engine** that helps users *discover and read programming books*.
+It intelligently **searches for books** using a pre-built index, provides "Did you mean?" suggestions, and offers
+*personalized recommendations* based on book details and user popularity. The system also tracks user clicks
+to continuously improve its search results and recommendations, presenting information through both command-line
+and graphical interfaces.
