+The GraphQL Java `RuntimeWiring.Builder` can be used to register custom scalar types, directives, type resolvers, ``DataFetcher``s, and more.
 You can declare `RuntimeWiringConfigurer` beans in your Spring config to get access to the `RuntimeWiring.Builder`.
 Spring Boot detects such beans and adds them to the {spring-graphql-docs}#execution-graphqlsource[GraphQlSource builder].
 
 Typically, however, applications will not implement `DataFetcher` directly and will instead create {spring-graphql-docs}#controllers[annotated controllers].
-Spring Boot will automatically detect `@Controller` classes with annotated handler methods and register those as `DataFetcher`s.

-=== Exceptions Handling
+=== Exception Handling
 Spring GraphQL enables applications to register one or more Spring `DataFetcherExceptionResolver` components that are invoked sequentially.
 The Exception must be resolved to a list of `graphql.GraphQLError` objects, see {spring-graphql-docs}#execution-exceptions[Spring GraphQL exception handling documentation].
 Spring Boot will automatically detect `DataFetcherExceptionResolver` beans and register them with the `GraphQlSource.Builder`.
