  * `graphiql`: If `True`, may present [GraphiQL](https://github.com/graphql/graphiql) when loaded directly from a browser (a useful tool for debugging and exploration).
  * `graphiql_template`: Inject a Jinja template string to customize GraphiQL.
  * `batch`: Set the GraphQL view as batch (for using in [Apollo-Client](http://dev.apollodata.com/core/network.html#query-batching) or [ReactRelayNetworkLayer](https://github.com/nodkz/react-relay-network-layer))
+ * `middleware`: A list of graphql [middlewares](http://docs.graphene-python.org/en/latest/execution/middleware/).
 
 You can also subclass `GraphQLView` and overwrite `get_root_value(self, request)` to have a dynamic root value
 per request.

+# Contributing
+
+Thanks for helping to make flask-graphql awesome!
+
+We welcome all kinds of contributions:
+
+- Bug fixes
+- Documentation improvements
+- New features
+- Refactoring & tidying
+
+
+## Getting started
+
+If you have a specific contribution in mind, be sure to check the [issues](https://github.com/graphql-python/flask-graphql/issues) and [projects](https://github.com/graphql-python/flask-graphql/projects) in progress - someone could already be working on something similar and you can help out.
+
+
+## Project setup
+
+After cloning this repo, ensure dependencies are installed by running:
+
+```sh
+make dev-setup
+```
+
+## Running tests
+
+After developing, the full test suite can be evaluated by running:
+
+```sh
+make tests
+```
+
+## Development on Conda
+
+In order to run `tox` command on conda, you must create a new env (e.g. `flask-grapqhl-dev`) with the following command:
+
+```sh
+conda create -n flask-grapqhl-dev python=3.8
+```
+
+Then activate the environment with `conda activate flask-grapqhl-dev` and install [tox-conda](https://github.com/tox-dev/tox-conda):
+
+```sh
+conda install -c conda-forge tox-conda
+```
+
+Uncomment the `requires = tox-conda` line on `tox.ini` file and that's it! Run `tox` and you will see all the environments being created and all passing tests. :rocket:

-Flask-GraphQL
-=============
-
-|Build Status| |Coverage Status| |PyPI version|
-
-Adds GraphQL support to your Flask application.
-
-Usage
------
-
-Just use the ``GraphQLView`` view from ``flask_graphql``
-
-.. code:: python
-
-    from flask_graphql import GraphQLView
-
-    app.add_url_rule('/graphql', view_func=GraphQLView.as_view('graphql', schema=schema, graphiql=True))
-
-    # Optional, for adding batch query support (used in Apollo-Client)
-    app.add_url_rule('/graphql/batch', view_func=GraphQLView.as_view('graphql', schema=schema, batch=True))
-
-This will add ``/graphql`` and ``/graphiql`` endpoints to your app.
-
-Supported options
-~~~~~~~~~~~~~~~~~
-
--  ``schema``: The ``GraphQLSchema`` object that you want the view to
-   execute when it gets a valid request.
--  ``context``: A value to pass as the ``context`` to the ``graphql()``
-   function.
--  ``root_value``: The ``root_value`` you want to provide to
-   ``executor.execute``.
--  ``pretty``: Whether or not you want the response to be pretty printed
-   JSON.
--  ``executor``: The ``Executor`` that you want to use to execute
-   queries.
--  ``graphiql``: If ``True``, may present
-   `GraphiQL <https://github.com/graphql/graphiql>`__ when loaded
-   directly from a browser (a useful tool for debugging and
-   exploration).
--  ``graphiql_template``: Inject a Jinja template string to customize
-   GraphiQL.
--  ``batch``: Set the GraphQL view as batch (for using in
-   `Apollo-Client <http://dev.apollodata.com/core/network.html#query-batching>`__
-   or
-   `ReactRelayNetworkLayer <https://github.com/nodkz/react-relay-network-layer>`__)
-
-You can also subclass ``GraphQLView`` and overwrite
-``get_root_value(self, request)`` to have a dynamic root value per
-request.
-
-.. code:: python
-
-    class UserRootValue(GraphQLView):
-        def get_root_value(self, request):
-            return request.user
-

 ## Getting started
 
-If you have a specific contribution in mind, be sure to check the [issues](https://github.com/graphql-python/flask-graphql/issues) and [projects](https://github.com/graphql-python/flask-graphql/projects) in progress - someone could already be working on something similar and you can help out.

 ## Project setup
 
-After cloning this repo, ensure dependencies are installed by running:
+### Development with virtualenv (recommended)
+
+After cloning this repo, create a virtualenv:
+
+```console
+virtualenv flask-graphql-dev
+```
+
+Activate the virtualenv and install dependencies by running:
+
+```console
+python pip install -e ".[test]"
+```
+
+If you are using Linux or MacOS, you can make use of Makefile command 
+`make dev-setup`, which is a shortcut for the above python command.
+
+### Development on Conda
+
+You must create a new env (e.g. `flask-graphql-dev`) with the following command:
 
 ```sh
-make dev-setup
+conda create -n flask-graphql-dev python=3.8
 ```
 
+Then activate the environment with `conda activate flask-graphql-dev`.
+
+Proceed to install all dependencies by running:
+
+```console
+python pip install -e ".[test]"
+```
+
+And you ready to start development!
+
 ## Running tests
 
 After developing, the full test suite can be evaluated by running:
 
 ```sh
-make tests
+pytest tests --cov=flask_graphql -vv
 ```
 
-## Development on Conda
+If you are using Linux or MacOS, you can make use of Makefile command 
+`make tests`, which is a shortcut for the above python command.
 
-In order to run `tox` command on conda, you must create a new env (e.g. `flask-grapqhl-dev`) with the following command:
+You can also test on several python environments by using tox.
 
-```sh
-conda create -n flask-grapqhl-dev python=3.8
+### Running tox on virtualenv
+
+Install tox:
+
+```console
+pip install tox
 ```
 
-Then activate the environment with `conda activate flask-grapqhl-dev` and install [tox-conda](https://github.com/tox-dev/tox-conda):
+Run `tox` on your virtualenv (do not forget to activate it!) 
+and that's it! 
+
+### Running tox on Conda
+
+In order to run `tox` command on conda, install
+[tox-conda](https://github.com/tox-dev/tox-conda):
 
 ```sh
 conda install -c conda-forge tox-conda
 ```
 
-Uncomment the `requires = tox-conda` line on `tox.ini` file and that's it! Run `tox` and you will see all the environments being created and all passing tests. :rocket:
+This install tox underneath so no need to install it before.
+
+Then uncomment the `requires = tox-conda` line on `tox.ini` file.
+
+Run `tox` and you will see all the environments being created

 ```
 
-This will add `/graphql` and `/graphiql` endpoints to your app.
+This will add `/graphql` endpoint to your app and enable the GraphiQL IDE.
+
+### Special Note for Graphene v3
+
+If you are using the `Schema` type of [Graphene](https://github.com/graphql-python/graphene) library, be sure to use the `graphql_schema` attribute to pass as schema on the `GraphQLView` view. Otherwise, the `GraphQLSchema` from `graphql-core` is the way to go.
+
+More info at [Graphene v3 release notes](https://github.com/graphql-python/graphene/wiki/v3-release-notes#graphene-schema-no-longer-subclasses-graphqlschema-type) and [GraphQL-core 3 usage](https://github.com/graphql-python/graphql-core#usage).
+
+
+### Supported options for GraphQLView
 
-### Supported options
  * `schema`: The `GraphQLSchema` object that you want the view to execute when it gets a valid request.
- * `context`: A value to pass as the `context` to the `graphql()` function.
- * `root_value`: The `root_value` you want to provide to `executor.execute`.
+ * `context`: A value to pass as the `context_value` to graphql `execute` function. By default is set to `dict` with request object at key `request`.
+ * `root_value`: The `root_value` you want to provide to graphql `execute`.
  * `pretty`: Whether or not you want the response to be pretty printed JSON.
- * `executor`: The `Executor` that you want to use to execute queries.
  * `graphiql`: If `True`, may present [GraphiQL](https://github.com/graphql/graphiql) when loaded directly from a browser (a useful tool for debugging and exploration).
+ * `graphiql_version`: The graphiql version to load. Defaults to **"1.0.3"**.
  * `graphiql_template`: Inject a Jinja template string to customize GraphiQL.
+ * `graphiql_html_title`: The graphiql title to display. Defaults to **"GraphiQL"**.
  * `batch`: Set the GraphQL view as batch (for using in [Apollo-Client](http://dev.apollodata.com/core/network.html#query-batching) or [ReactRelayNetworkLayer](https://github.com/nodkz/react-relay-network-layer))
  * `middleware`: A list of graphql [middlewares](http://docs.graphene-python.org/en/latest/execution/middleware/).
+ * `encode`: the encoder to use for responses (sensibly defaults to `graphql_server.json_encode`).
+ * `format_error`: the error formatter to use for responses (sensibly defaults to `graphql_server.default_format_error`.
+ * `subscriptions`: The GraphiQL socket endpoint for using subscriptions in graphql-ws.
+ * `headers`: An optional GraphQL string to use as the initial displayed request headers, if not provided, the stored headers will be used.
+ * `default_query`: An optional GraphQL string to use when no query is provided and no stored query exists from a previous session. If not provided, GraphiQL will use its own default query.
+* `header_editor_enabled`: An optional boolean which enables the header editor when true. Defaults to **false**.
+* `should_persist_headers`:  An optional boolean which enables to persist headers to storage when true. Defaults to **false**.
 
 You can also subclass `GraphQLView` and overwrite `get_root_value(self, request)` to have a dynamic root value
 per request.

-# Contributing
-
-Thanks for helping to make flask-graphql awesome!
-
-We welcome all kinds of contributions:
-
-- Bug fixes
-- Documentation improvements
-- New features
-- Refactoring & tidying
-
-
-## Getting started
-
-If you have a specific contribution in mind, be sure to check the [issues](https://github.com/graphql-python/flask-graphql/issues) and [pull requests](https://github.com/graphql-python/flask-graphql/pulls) in progress - someone could already be working on something similar and you can help out.
-
-
-## Project setup
-
-### Development with virtualenv (recommended)
-
-After cloning this repo, create a virtualenv:
-
-```console
-virtualenv flask-graphql-dev
-```
-
-Activate the virtualenv and install dependencies by running:
-
-```console
-python pip install -e ".[test]"
-```
-
-If you are using Linux or MacOS, you can make use of Makefile command 
-`make dev-setup`, which is a shortcut for the above python command.
-
-### Development on Conda
-
-You must create a new env (e.g. `flask-graphql-dev`) with the following command:
-
-```sh
-conda create -n flask-graphql-dev python=3.8
-```
-
-Then activate the environment with `conda activate flask-graphql-dev`.
-
-Proceed to install all dependencies by running:
-
-```console
-python pip install -e ".[test]"
-```
-
-And you ready to start development!
-
-## Running tests
-
-After developing, the full test suite can be evaluated by running:
-
-```sh
-pytest tests --cov=flask_graphql -vv
-```
-
-If you are using Linux or MacOS, you can make use of Makefile command 
-`make tests`, which is a shortcut for the above python command.
-
-You can also test on several python environments by using tox.
-
-### Running tox on virtualenv
-
-Install tox:
-
-```console
-pip install tox
-```
-
-Run `tox` on your virtualenv (do not forget to activate it!) 
-and that's it! 
-
-### Running tox on Conda
-
-In order to run `tox` command on conda, install
-[tox-conda](https://github.com/tox-dev/tox-conda):
-
-```sh
-conda install -c conda-forge tox-conda
-```
-
-This install tox underneath so no need to install it before.
-
-Then uncomment the `requires = tox-conda` line on `tox.ini` file.
-
-Run `tox` and you will see all the environments being created 
-and all passing tests. :rocket:
