GraphQL is an API query language that allows clients to ask for exactly what they need and nothing more makes it easier to evolve APIs over time.

This course is divided into three parts, Part 1- Build a GraphQL API, Part 2- Publish Your API, and Part-3 Use Your API. 

In the first part, you will cover topics ranging from basic GraphQL, Building GraphQL Schema, Taking User Input, Adding Flexibility, Making a Change with Mutations, and Going Live with Subscriptions.

In the second part, you will cover topics ranging from Resolution Middleware, Securing with Authentication and Authorization, and Tuning Resolution.

The third part will cover topics ranging from Driving Phoenix Actions with GraphQL, Integrating with the Frontend and GraphQL Types. Upon completing this course, you will have sufficient foundational knowledge of GraphQL, and you can build, publish and use your API in GraphQL.

## Defining a root mutation type
We need to define a root mutation type to support mutation operations, just as we did for queries. This will be used as the entry point for GraphQL mutation operations. The mutation fields that we add define the complete list of capabilities available to the API users to modify data. We define the root mutation type by using the mutation macro in our schema file, as shown here:
