 What is ``Dependency Injector``?
 ================================
 
-``Dependency Injector`` is a dependency injection microframework for Python.
-It was designed to be a unified and developer-friendly tool that helps
-implement a dependency injection design pattern in a formal, pretty, and
-Pythonic way.
+``Dependency Injector`` is a dependency injection framework for Python.
 
-The key features of the *Dependency Injector* framework are:
+Why do I need it?
+=================
 
-+ Easy, smart, and pythonic style.
-+ Obvious and clear structure.
-+ Extensibility and flexibility.
-+ High performance.
-+ Memory efficiency.
-+ Thread safety.
-+ Documented.
-+ Semantically versioned.
+``Dependency Injector`` helps you improve application structure.
 
-*Dependency Injector* containers and providers are implemented as C extension 
-types using Cython.
+With the ``Dependency Injector`` you keep **application structure in one place**.
+This place is called **the container**. You use the container to manage all the components of the application. All the component dependencies are defined explicitly. This provides the control on the application structure. It is **easy to understand and change** it.

+
+*The container is like a map of your application. You always know what depends on what.*

+    from dependency_injector.ext import flask
+    from github import Github
+
+    from . import services, views

+
+How to install?
+---------------
+
+- The package is available on the `PyPi`_::
 
     pip install dependency-injector
 
-Documentation
--------------
-
-The *Dependency Injector* documentation is hosted on ReadTheDocs:
-
-- `User's guide`_
-- `API docs`_
-
-Dependency injection
---------------------
-
-`Dependency injection`_ is a software design pattern that implements 
-`Inversion of control`_ to resolve dependencies. Formally, if object **A** 
-depends on object **B**, object **A** must not create or import object **B** 
-directly. Instead of this object **A** must provide a way to *inject* 
-object **B**. The responsibilities of objects creation and dependency
-injection are delegated to external code - the *dependency injector*. 
-
-Popular terminology of the dependency injection pattern:
-
-+ Object **A**, which depends on object **B**, is often called - 
-  the *client*.
-+ Object **B**, which is depended on, is often called - the *service*.
-+ External code that is responsible for creation of objects and injection 
-  of dependencies is often called - the *dependency injector*.
-
-There are several ways to inject a *service* into a *client*: 
-
-+ by passing it as an ``__init__`` argument (constructor / initializer
-  injection)
-+ by setting it as an attribute's value (attribute injection)
-+ by passing it as a method's argument (method injection)
-
-The dependency injection pattern has few strict rules that should be followed:
-
-+ The *client* delegates to the *dependency injector* the responsibility 
-  of injecting its dependencies - the *service(s)*.
-+ The *client* doesn't know how to create the *service*, it knows only 
-  the interface of the *service*. The *service* doesn't know that it is used by 
-  the *client*.
-+ The *dependency injector* knows how to create the *client* and 
-  the *service*. It also knows that the *client* depends on the *service*, 
-  and knows how to inject the *service* into the *client*.
-+ The *client* and the *service* know nothing about the *dependency injector*.
-
-The dependency injection pattern provides the following advantages: 
-
-+ Control of application structure.
-+ Decreased coupling of application components.
-+ Increased code reusability.
-+ Increased testability.
-+ Increased maintainability.
-+ Reconfiguration of a system without rebuilding.
-
-Example of dependency injection
--------------------------------
-
-Let's go through next example:
-
-.. image:: https://raw.githubusercontent.com/wiki/ets-labs/python-dependency-injector/img/engines_cars/diagram.png
-    :width: 100%
-    :align: center
-
-Listing of ``example.engines`` module:
-
-.. code-block:: python
-
-    """Dependency injection example, engines module."""
-
-
-    class Engine:
-        """Example engine base class.
-
-        Engine is a heart of every car. Engine is a very common term and could be
-        implemented in very different ways.
-        """
-
-
-    class GasolineEngine(Engine):
-        """Gasoline engine."""
-
-
-    class DieselEngine(Engine):
-        """Diesel engine."""
-
-
-    class ElectricEngine(Engine):
-        """Electric engine."""
-
-Listing of ``example.cars`` module:
-
-.. code-block:: python
-
-    """Dependency injection example, cars module."""
-
-
-    class Car:
-        """Example car."""
-
-        def __init__(self, engine):
-            """Initializer."""
-            self._engine = engine  # Engine is injected
-
-The next example demonstrates the creation of several cars with different engines:
-
-.. code-block:: python
-
-    """Dependency injection example, Cars & Engines."""
-
-    import example.cars
-    import example.engines
-
-
-    if __name__ == '__main__':
-        gasoline_car = example.cars.Car(example.engines.GasolineEngine())
-        diesel_car = example.cars.Car(example.engines.DieselEngine())
-        electric_car = example.cars.Car(example.engines.ElectricEngine())
-
-While the previous example demonstrates the advantages of dependency injection,
-there is a disadvantage demonstrated as well - the creation of a car requires 
-additional code to specify its dependencies. However, this disadvantage
-could be avoided by using a dependency injection framework for the creation of 
-an inversion of control container (IoC container).
-
-Here's an example of the creation of several inversion of control containers
-(IoC containers) using *Dependency Injector*:
-
-.. code-block:: python
-
-    """Dependency injection example, Cars & Engines IoC containers."""
-
-    import example.cars
-    import example.engines
-
-    import dependency_injector.containers as containers
-    import dependency_injector.providers as providers
-
-
-    class Engines(containers.DeclarativeContainer):
-        """IoC container of engine providers."""
-
-        gasoline = providers.Factory(example.engines.GasolineEngine)
-
-        diesel = providers.Factory(example.engines.DieselEngine)
-
-        electric = providers.Factory(example.engines.ElectricEngine)
-
-
-    class Cars(containers.DeclarativeContainer):
-        """IoC container of car providers."""
-
-        gasoline = providers.Factory(example.cars.Car,
-                                     engine=Engines.gasoline)
-
-        diesel = providers.Factory(example.cars.Car,
-                                   engine=Engines.diesel)
-
-        electric = providers.Factory(example.cars.Car,
-                                     engine=Engines.electric)
-
-
-    if __name__ == '__main__':
-        gasoline_car = Cars.gasoline()
-        diesel_car = Cars.diesel()
-        electric_car = Cars.electric()
-
-Dependency Injector structure
------------------------------
-
-*Dependency Injector* is a microframework and has a simple structure.
-
-There are two main entities: providers and containers.
-
-.. image:: https://raw.githubusercontent.com/wiki/ets-labs/python-dependency-injector/img/internals.png
-    :width: 100%
-    :align: center
-
-Providers
-~~~~~~~~~
-
-Providers describe strategies of accessing objects. They define how particular 
-objects are provided.
-
-- **Provider** - base provider class.
-- **Callable** - provider that calls a wrapped callable on every call. Supports 
-  positional and keyword argument injections.
-- **Factory** - provider that creates new instance of specified class on every 
-  call. Supports positional and keyword argument injections, as well as 
-  attribute injections.
-- **Singleton** - provider that creates new instance of specified class on its
-  first call and returns the same instance on every next call. Supports
-  position and keyword argument injections, as well as attribute injections.
-- **Object** - provider that returns provided instance "as is".
-- **ExternalDependency** - provider that can be useful for development of 
-  self-sufficient libraries, modules, and applications that require external
-  dependencies.
-- **Configuration** - provider that helps with implementing late static binding 
-  of configuration options - use first, define later.
-
-Containers
-~~~~~~~~~~
-
-Containers are collections of providers. The main purpose of containers is to 
-group providers.
-
-- **DeclarativeContainer** - is an inversion of control container that can be 
-  defined in a declarative manner. It covers most of the cases where a list of
-  providers that is be included in a container is deterministic 
-  (that means the container will not change its structure in runtime).
-- **DynamicContainer** - is an inversion of control container with a dynamic 
-  structure. It covers most of the cases where a  list of providers that 
-  would be included in container is non-deterministic and depends on  the
-  application's flow or its configuration (container's structure could be 
-  determined just after the application starts and might perform some initial 
-  work, like parsing a list of container providers from a configuration).
-
-Dependency Injector in action
------------------------------
-
-The brief example below is a simplified version of inversion of control 
-containers from a real-life application. The example demonstrates the usage
-of *Dependency Injector* inversion of control container and  providers for
-specifying application components and their dependencies on each other in one
-module. Besides other previously mentioned advantages, it shows a great
-opportunity to control and manage application's structure in one place.

+    * Restarting with fsevents reloader
+    * Debugger is active!
+    * Debugger PIN: 473-587-859

+After that visit http://127.0.0.1:5000/ in your browser.
+
+.. note::
+
+
+   Github has a rate limit. When thre rate limit is exceed you will see an exception
+   ``github.GithubException.RateLimitExceededException``. For unauthenticated requests, the rate
+   limit allows for up to 60 requests per hour. To extend the limit to 5000 requests per hour you
+   need to set personal access token.
+
+   It's easy:
+
+   - Follow this `guide <https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token>`_ to create a token.
+   - Set a token to the environment variable:
+
+   .. code-block:: bash
+
+      export GITHUB_TOKEN=<your token>
+
+   - Restart the app with ``flask run``
+
+   `Read more on Github rate limit <https://developer.github.com/v3/#rate-limiting>`_
+
+Test
+----
+
+This application comes with unit tests.
+
+To run the tests do:
+
+.. code-block:: bash
+
+   py.test githubnavigator/tests.py --cov=githubnavigator
+
+The output should be something like:
