-`graphql-component` lets you build a schema progressively through a tree (faciliated through `imports`) of GraphQLComponent instances. Each GraphQLComponent instance encapsulates an executable GraphQL schema, specifically a `graphql-js` GraphQLSchema object. See the API below, but the encapsulated schema is accessible through a simple `schema` getter on a given `GraphQLComponent` instance.

 Generally speaking, each instance of `GraphQLComponent` has reference to an instance of [`GraphQLSchema`](https://graphql.org/graphql-js/type/#graphqlschema). This instance of `GraphQLSchema` is built in a several ways, depending on the options passed to a given `GraphQLComponent`'s constructor.

 ### Running examples:
 * composition: `npm run start-composition`
-* fedration: `npm run start-federation`
+* federation: `npm run start-federation`
 * go to `localhost:4000/graphql`
   * for composition this will bring up the GraphQL Playground for a plain old Apollo Server
