 RabbitMQ supervisor bundle
 ==========================
 
-Symfony 2 bundle to automatically create and update supervisor configurations for RabbitMQ consumer daemons
+[![Latest Stable Version](https://poser.pugx.org/phobetor/rabbitmq-supervisor-bundle/v/stable.png)](https://packagist.org/packages/phobetor/rabbitmq-supervisor-bundle) [![License](https://poser.pugx.org/phobetor/rabbitmq-supervisor-bundle/license.png)](https://packagist.org/packages/phobetor/rabbitmq-supervisor-bundle)
+
+Symfony 2 bundle to automatically create and update supervisor configurations for `oldsound/rabbitmq-bundle` RabbitMQ consumer daemons.
+
+## In a nutshell | tl;dr
+
+If you use `oldsound/rabbitmq-bundle` to handle the communication with RabbitMQ, just add this bundle and run
+```sh
+app/console rabbitmq-supervisor:rebuild
+```
+to get a running `supervisord` instance that automatically manages all your consumer daemons.
+When your worker configuration or your code changes, run
+```sh
+app/console rabbitmq-supervisor:rebuild
+```
+again and all the daemons will be updated.
+
+## Installation
+
+Add bundle via command line
+```sh
+php composer.phar require phobetor/rabbitmq-supervisor-bundle
+```
+
+or manually to `composer.json` file
+```js
+{
+    "require": {
+        "phobetor/rabbitmq-supervisor-bundle": "~1.3"
+    }
+}
+```
+
+Fetch the needed files:
+```bash
+$ php composer.phar update phobetor/rabbitmq-supervisor-bundle
+```
+
+This will install the bundle to your project’s `vendor` directory.
+
+Add the bundle to your project’s `AppKernel`:
+```php
+<?php
+// app/AppKernel.php
+
+public function registerBundles()
+{
+    $bundles = array(
+        // […]
+        new Phobetor\RabbitMqSupervisorBundle\RabbitMqSupervisorBundle(),
+    );
+}
+```
+
+## Zero Configuration
+
+RabbitMQ supervisor bundle works out of the box with a predefined configuration. If you leave it this way you will end
+up with this directory structure:
+```sh
+app/supervisor/
+└── dev
+    ├── logs
+    │   ├── stderr.log
+    │   └── stdout.log
+    ├── supervisord.conf
+    ├── supervisord.log
+    ├── supervisor.pid
+    ├── supervisor.sock
+    └── worker
+        ├── queue1.conf
+        ├── queue2.conf
+        ├── queue3.conf
+        └── queue4.conf
+```
+
+## Advanced configuration
+
+All the paths and commands can be changed in `app/config/config.yml`:
+```yml
+rabbit_mq_supervisor:
+    supervisor_instance_identifier:     instance_name
+    paths:
+        workspace_directory:            /path/to/workspace/
+        configuration_file:             /path/to/workspace/supervisord.conf
+        pid_file:                       /path/to/workspace/supervisord.pid
+        sock_file:                      /path/to/workspace/supervisord.sock
+        log_file:                       /path/to/workspace/supervisord.log
+        worker_configuration_directory: /path/to/workspace/worker/
+        worker_output_log_file:         /path/to/workspace/logs/%kernel.environment%.log
+        worker_error_log_file:          /path/to/workspace/logs/%kernel.environment%.log
+    commands:
+        rabbitmq_consumer:              user-specific-command:consumer -m %%1$d %%2$s
+        rabbitmq_multiple_consumer:     user-specific-command:multiple-consumer -m %%1$d %%2$s
+```
+
+## Usage
+
+Build or rebuild the supervisor and worker configuration and start the daemon:
+```sh
+app/console rabbitmq-supervisor:rebuild
+```
+
+Control the supervisord daemon:
+```sh
+app/console rabbitmq-supervisor:control stop
+app/console rabbitmq-supervisor:control start
+app/console rabbitmq-supervisor:control restart
+app/console rabbitmq-supervisor:control hup
+```
