-Bundles mini application example
---------------------------------
-
-.. currentmodule:: dependency_injector.containers
-
-"Bundles" is an example mini application that is intended to demonstrate the
-power of dependency injection for creation of re-usable application components
-("bundles") with 100% transparency of their dependencies.
-
-Example application
-~~~~~~~~~~~~~~~~~~~
-
-"Bundles" mini application has next structure:
-
-.. code-block:: bash
-
-    bundles/
-        bundles/               <-- Bundles package
-            photos/            <-- Photos bundle
-                __init__.py    <-- Photos bundle dependency injection container
-                entities.py
-                repositories.py
-            users/             <-- Users bundle
-                __init__.py    <-- Users bundle dependency injection container
-                entities.py
-                repositories.py
-        run.py                 <-- Entrypoint
-
-
-IoC containers
-~~~~~~~~~~~~~~
-
-Next two listings show :py:class:`DeclarativeContainer`'s for "users" and 
-"photos" bundles.
-
-Listing of ``bundles/users/__init__.py``:
-
-.. literalinclude:: ../../examples/miniapps/bundles/bundles/users/__init__.py
-   :language: python
-
-.. note::
-
-    - ``Users`` container has dependency on database.
-
-Listing of ``bundles/photos/__init__.py``:
-
-.. literalinclude:: ../../examples/miniapps/bundles/bundles/photos/__init__.py
-   :language: python
-
-.. note::
-
-    - ``Photos`` container has dependencies on database and file storage.
-
-Run application
-~~~~~~~~~~~~~~~
-
-Finally, both "bundles" are initialized by providing needed dependencies.
-Initialization of dependencies happens right in the runtime, not earlier.
-Generally, it means, that any part of any bundle could be overridden on the
-fly.
-
-Listing of ``run.py``:

+Decoupled packages example (multiple containers)
+================================================
+
+.. meta::
+   :keywords: Python,Dependency Injection,Inversion of Control,Container,Example,Application,
+              Framework,AWS,boto3,client
+   :description: This example shows how to use Dependency Injector to create Python decoupled packages.
+                 To achieve a decoupling each package has a container with the components. When
+                 a component needs a dependency from the outside of the package scope we use the
+                 Dependency provider. The package container has no knowledge on where the
+                 dependencies come from. It states a need that the dependencies must be provided.
+                 This helps to decouple a package from the 3rd party dependencies and other
+                 packages.
+
+This example shows how to use ``Dependency Injector`` to create decoupled packages.
+
+To achieve a decoupling each package has a container with the components. When a component needs a
+dependency from the outside of the package scope we use the ``Dependency`` provider. The package
+container has no knowledge on where the dependencies come from. It states a need that the
+dependencies must be provided. This helps to decouple a package from the 3rd party dependencies
+and other packages.
+
+To wire the packages we use an application container. Application container has all 3rd party
+dependencies and package containers. It wires the packages and dependencies to create a
+complete application.
+
+We build an example micro application that consists of 3 packages:
+
+- ``user`` - a package with user domain logic, depends on a database
+- ``photo`` - a package with photo domain logic, depends on a database and AWS S3
+- ``analytics`` - a package with analytics domain logic, depends on the  ``user`` and ``photo``
+  package components

+Application container

+
+Application container consists of all packages and 3rd party dependencies. Its role is to wire
+everything together in a complete application.

+
+.. note::
+   Package ``analytics`` has dependencies on the repositories from the ``user`` and
+   ``photo`` packages. This is an example of how you can pass the dependencies from one package
+   to another.
