 ## Context
 
-Apollo GraphQL offers 2 approaches to create and maintain a GraphQL schema: Code First and Schema First. We have to choose one of them to start developing our Graph.
+Apollo GraphQL offers 2 approaches to create and maintain a GraphQL schema: Code
+First and Schema First. We have to choose one of them to start developing our
+Graph.
 
 ## Decision
 
-We are using the Code First approach which generates a GraphQL schema from TypeScript classes and their annotations.
-With the Code First approach, we have type safety out of the box and we can generate the schema automatically.
-Furthermore, the knowledge about GraphQL schema specifications is rare in the team, which also contributed to this decision.

 ## Consequences
 
 - It is easier to setup, maintain and refactor.
-- We can think in TypeScript models and types while developing our schema, which should enable us to develop faster.
-- We might hit a barrier which we currently can not see with the Code First Approach when our schema gets complex.
