+# Online Book Store
+
+## Project Overview
+
+The online bookstore management system offers a user-friendly interface for customers and administrators while ensuring security through authentication and authorization using JWT tokens. Customers can easily sign up, browse books, manage their shopping carts, place orders, and review their order history. Administrators, on the other hand, have tools to efficiently handle the book catalog, categories, and monitor order statuses. The project's aim is to create a convenient API that enhances the online book purchasing experience and simplifies administrative tasks.
