 An implementation of GraphQL's type system in Dart. Supports any platform where Dart runs.
+The decisions made in the design of this library were done to make the experience
+as similar to the JavaScript reference implementation as possible, and to also
+correctly implement the official specification.

 ```dart
 /// A non-nullable list of non-nullable integers
 listType(graphQLInt.nonNullable()).nonNullable();
+```
+
+### Input values and parameters
+Take the following GraphQL query:
+
+```graphql
+{
+   anime {
+     characters(title: "Hunter x Hunter") {
+        name
+        age
+     }
+   }
+}
+```
+
+The field `characters` accepts a parameter, `title`. To reproduce this in
+`package:graphql_schema`, use `GraphQLFieldInput`:
+
+```dart
+final GraphQLObjectType queryType = objectType('AnimeQuery', fields: [
+  field('characters',
+    listType(characterType.nonNullable()),
+    inputs: [
+      new GraphQLFieldInput('title', graphQLString.nonNullable())
+    ]
+  ),
+]);
+
+final GraphQLObjectType characterType = objectType('Character', fields: [
+  field('name', graphQLString),
+  field('age', graphQLInt),
+]);
+```
+
+In the majority of cases where you use GraphQL, you will be delegate the
+actual fetching of data to a database object, or some asynchronous resolver
+function.
+
+`package:graphql_schema` includes this functionality in the `resolve` property,
+which is passed a context object and a `Map<String, dynamic>` of arguments.
+
+A hypothetical example of the above might be:
+
+```dart
+var field = field(
+  'characters',
+  graphQLString,
+  resolve: (_, args) async {
+    return await myDatabase.findCharacters(args['title']);
+  },
+);
 ```
