+# Cart Enrolment Method
+
+This is a complete shopping cart plugin for Moodle that adds a "Cart" enrolment
+method to courses, allowing users to add courses to their cart and complete the
+payment using the available payment methods in Moodle.
+
+Users can view their shopping cart using the cart icon in the top navigation bar 
+and see their purchase history through the "My Purchases" option in the user menu.
+Additionally, users can add courses to their cart before logging in, with the cart 
+information stored in a cookie. After logging in, the cart is transferred from the 
+cookie to the database, allowing the user to complete the payment.
+
+This plugin allows the admin to set a discount amount or percentage for each course. 
+Additionally, by implementing the `enrol_cart\object\CouponInterface` class and setting 
+the `coupon_class` in the cart enrollment settings, users can use discount coupons during 
+checkout.
