 Serverless Full Stack implementation on Azure of [TodoMVC](http://todomvc.com/) app with support both for REST and GraphQL endpoints via [Prisma](https://www.prisma.io/)
 
+This sample is a variation of the Full-Stack MVC Todo sample described here: [TodoMVC Full Stack with Azure Static Web Apps, Node and Azure SQL](https://devblogs.microsoft.com/azure-sql/todomvc-full-stack-with-azure-static-web-apps-node-and-azure-sql/). The difference, of course, is the use of Prisma to have **a model-first approach and to support both the REST and GraphQL endpoints**.
+
+This means you can use Typescript to query your database and Prisma will take care of generating and executing the correct SQL query. This way you can focus on creating amazing solution while still having all the power and the feature of Azure SQL at your service. Just like magic!
