+# Container Interoperability
+
+[![Latest Stable Version](https://poser.pugx.org/container-interop/container-interop/v/stable.png)](https://packagist.org/packages/container-interop/container-interop)
+
+*container-interop* tries to identify and standardize features in *container* objects (service locators,
+dependency injection containers, etc.) to achieve interopererability.
+
+Through discussions and trials, we try to create a standard, made of common interfaces but also recommendations. 
+
+If PHP projects that provide container implementations begin to adopt these common standards, then PHP
+applications and projects that use containers can depend on the common interfaces instead of specific
+implementations. This facilitates a high-level of interoperability and flexibility that allows users to consume
+*any* container implementation that can be adapted to these interfaces.
+
+The work done in this project is not officially endorsed by the [PHP-FIG](http://www.php-fig.org/), but it is being
+worked on by members of PHP-FIG and other good developers. We adhere to the spirit and ideals of PHP-FIG, and hope
+this project will pave the way for one or more future PSRs.
+
+
+## Installation
+
+You can install this package through Composer:
+
+```json
+{
+    "require": {
+        "container-interop/container-interop": "~1.0"
+    }
+}
+```
+
+The packages adheres to the [SemVer](http://semver.org/) specification, and there will be full backward compatibility
+between minor versions.
+
+## Standards
+
+### Available
+
+- [`ContainerInterface`](src/Interop/Container/ContainerInterface.php).
+[Description](docs/ContainerInterface.md) [Meta Document](docs/ContainerInterface-meta.md).
+Describes the interface of a container that exposes methods to read its entries.
+- [*Delegate lookup feature*](docs/Delegate-lookup.md).
+[Meta Document](docs/Delegate-lookup-meta.md).
+Describes the ability for a container to delegate the lookup of its dependencies to a third-party container. This 
+feature lets several containers work together in a single application.
+

+
+## Workflow
+
+Everyone is welcome to join and contribute.
+
+The general workflow looks like this:
+
+1. Someone opens a discussion (GitHub issue) to suggest an interface
+1. Feedback is gathered
+1. The interface is added to a development branch
+1. We release alpha versions so that the interface can be experimented with
+1. Discussions and edits ensue until the interface is deemed stable by a general consensus
+1. A new minor version of the package is released
+
+We try to not break BC by creating new interfaces instead of editing existing ones.
+
+While we currently work on interfaces, we are open to anything that might help towards interoperability, may that
+be code, best practices, etc.
