 =============
 
 Creates an avenue for using ApiKey authentication for Symfony2. Requires FOSUserBundle.
+
+
+## Installation
+
+Requires composer, install as follows
+
+```sh
+composer require uecode/api-key-bundle dev-master
+```
+
+#### Enable Bundle
+
+Place in your `AppKernel.php` to enable the bundle
+
+```php
+<?php
+// app/AppKernel.php
+
+public function registerBundles()
+{
+    $bundles = array(
+        // ...
+        new Uecode\Bundle\ApiKeyBundle\UecodeApiKeyBundle(),
+    );
+}
+```
+#### Entities
+
+Assuming you already have a `User` class that extends the `FOSUserBundle`'s base user model,
+change that extend, so its extending `Uecode\Bundle\ApiKeyBundle\Model\ApiKeyUser`
+
+Then update your schema.
+
+#### Set up security
+
+In your security, change your provider to the service `uecode.api_key.provider.user_provider`
+
+```yml
+security:
+    providers:
+        db:
+            id: uecode.api_key.provider.user_provider
+
+    # Or
+
+    providers:
+        chain_provider:
+            chain:
+                providers: [db, memory]
+        memory: # .....
+        db:
+            id: uecode.api_key.provider.user_provider
+```
+
+After adding that, you can now add `api_key: true`, and `stateless: true` to any of your firewalls. 
+
+For Example:
+
+```yml
+security:
+    firewalls:
+        auth:
+            pattern: ^/api/*
+            api_key: true
+            stateless: true
+
+```
