+This demo application shows how you can write Wing applications with cloud primitives and custom abstractions into services, routes and listening to database changes.
+
+To use the application
+
+- Make sure you have Wing installed and clone the repo.
+- Run `wing it` in the `backend` project directory
+- The wing console will load in your browser. 
+- Go to http://localhost:5173/ to load the Vite application.
+- Click `Create Magical Space`
+- Add email address and files into the application.
+- Click `Share with Friends` to send emails to your selected friends.
+
+This application consists of a collection of cloud primitives with Wing and winglibs:
+
+- [Cloud API](https://www.winglang.io/docs/api/standard-library/cloud/api) - API for the frontend to add/edit and delete friends/spaces.
+- [Cloud functions](https://www.winglang.io/docs/api/standard-library/cloud/function) - Compute to process API requests, queues and database changes.
+- [Queues](https://www.winglang.io/docs/api/standard-library/cloud/queue) - To handle sending the email, configured DLQ on the queue
+- [winglib DynamoDB](https://www.winglang.io/docs/winglibs/dynamodb) - Single table design to store friends and spaces into the database.
+- [winglib email](https://www.winglang.io/docs/winglibs/email) - To send emails to friends.
