 ```bash
 composer require hecht-a/graphql-orm
 ```
+
+## Configuration
+Configure the GraphQL endpoint and entity mapping.
+
+Example :
+```yaml
+graphql_orm:
+    endpoint: 'http://localhost:4000'
+    max_depth: 3
+
+    mapping:
+        entity:
+            dir: '%kernel.project_dir%/src/GraphQL/Entity'
+            namespace: App\GraphQL\Entity
+        repository:
+            dir: '%kernel.project_dir%/src/GraphQL/Repository'
+            namespace: App\GraphQL\Repository
+```
+Options:
+
+- `endpoint` : GraphQL API endpoint.
+- `max_depth` : Maximum nested relation loading depth.
+- `mapping.entity` : Entity generation directory and namespace.
+- `mapping.repository` : Repository generation directory and namespace.
+
+---
+
+## Entity Generator
+GraphqlOrm provides a console wizard to generate entities and repositories.
+
+Create a new entity :
+
+```bash
+php bin/console graphqlorm:make:entity Task
+````
+
+The command generates :
+- Entity class
+- Repository class
+- Identifier property
+- Scalar properties
+- Relations
+
+The generator asks interactively :
+- GraphQL root name
+- Identifier field
+- Scalar properties
+- Relations
+
+Example wizard :
+```
+Add a property ? yes
+
+Property name:
+id
+
+Field name in GraphQL schema :
+id
+
+Identifier ? yes
+
+Type:
+int
+
+Nullable ? no
+
+Add a property ? yes
+
+Property name:
+title
+
+Field name in GraphQL schema :
+title
+
+Type:
+string
+
+Nullable ? no
+
+Add a property ? yes
+
+Property name:
+user
+
+Field name in GraphQL schema :
+user
+
+Type:
+relation
+```
+
+Relation wizard :
+```
+Target entity :
+> Us<TAB>
+User
+
+Relation type :
+object
+```
+Existing entities are automatically suggested using autocomplete.
+
+Generated example :
+```php
+#[GraphqlEntity('tasks', TaskRepository::class)]
+class Task
+{
+    #[GraphqlField(mappedFrom: 'id', identifier: true)]
+    private int $id;
+
+    #[GraphqlField(mappedFrom: 'title')]
+    private string $title;
+
+    #[GraphqlField(mappedFrom: 'user')]
+    private ?User $user = null;
+}
+```
+Repository :
+```php
+/**
+ * @extends GraphqlEntityRepository<Task>
+ * @method Task[] findAll()
+ * @method Task[] findBy(array $criteria)
+ */
+class TaskRepository extends GraphqlEntityRepository
+{
+    public function __construct(GraphqlManager $graphQLManager)
+    {
+        parent::__construct($graphQLManager, Task::class);
+    }
+}
+```
