-[Graphene](http://graphene-python.org) is a Python library for building GraphQL schemas/types fast and easily.
-
-- **Easy to use:** Graphene helps you use GraphQL in Python without effort.
-- **Relay:** Graphene has builtin support for Relay
-- **Django:** Automatic *Django model* mapping to Graphene Types. Check a fully working [Django](http://github.com/graphql-python/swapi-graphene) implementation
-
-Graphene also supports *SQLAlchemy*!
-
-*What is supported in this Python version?* **Everything**: Interfaces, ObjectTypes, Scalars, Unions and Relay (Nodes, Connections), in addition to queries, mutations and subscriptions.
-
-**NEW**!: [Try graphene online](http://graphene-python.org/playground/)
+A [Django](https://www.djangoproject.com/) integration for [Graphene](http://graphene-python.org/).

 ## Examples
 
-Here is one example for get you started:
+Here is a simple Django model:
 
 ```python
 from django.db import models
-from graphene_django import DjangoObjectType
 
 class UserModel(models.Model):
     name = models.CharField(max_length=100)
     last_name = models.CharField(max_length=100)
+```
+
+To create a GraphQL schema for it you simply have to write the following:
+
+```python
+from graphene_django import DjangoObjectType
 
 class User(DjangoObjectType):
     class Meta:
-        # This type will transform all the UserModel fields
-        # into Graphene fields automatically
         model = UserModel
 
-    # An extra field in the User Type
-    full_name = graphene.String()
+class Query(graphene.ObjectType):
+    users = graphene.List(User)
 
-    def resolve_full_name(self, args, context, info):
-        return "{} {}".format(self.name, self.last_name)
+    @graphene.resolve_only_args
+    def resolve_users(self):
+        return UserModel.objects.all()
+
+schema = graphene.Schema(query=QueryRoot)
 ```
 
-If you want to learn even more, you can also check the following [examples](examples/):
+Then you can simply query the schema:
+
+```python
+query = '''
+    query {
+      users {
+        name,
+        lastName
+      }
+    }
+'''
+result = schema.execute(query)
+```
+

 * **Relay Schema**: [Starwars Relay example](examples/starwars)
