 Integrates Behat with Symfony (`^3.4` and `^4.1`).
  
 Inspired by [Behat/Symfony2Extension](https://github.com/Behat/Symfony2Extension).
-
-## Differences
-
- -  Built-in `symfony` driver uses different kernel than the one that is used in the contexts.
-This means you can always change it to any other driver without any issues and 
-ensures that application behaviour will not be affected by stateful services.
-
-## Usage
-
-1. Install it:
-
-    ```bash
-    $ composer require friends-of-behat/symfony-extension --dev
-    ```
-
-2. Enable and configure in your Behat configuration:
-
-    ```yaml
-    # behat.yml
-    default:
-        # ...
-        extensions:
-            FriendsOfBehat\SymfonyExtension: ~
-    ```
-
-3. Good luck & have fun!

-## Configuration
-
-SymfonyExtension provides kind of autoconfiguration feature.
-When none explicit configuration is set, we will set for you sane default that will get you running fast.
-
-**Default Symfony 3 configuration**
-
-```
-FriendsOfBehat\SymfonyExtension:
-    kernel:
-        bootstrap: 'app/autoload.php' # you may want to use var/bootstrap.php.cache instead
-        path: app/AppKernel.php
-        class: 'AppKernel'
-        env: test
-        debug: true
-```
-
-**Default Symfony 4 configuration**
-
-```
-FriendsOfBehat\SymfonyExtension:
-    # .env.dist file will be used if .env file does not exist
-    env_file: .env
-    kernel:
-        bootstrap: ~
-        path: src/Kernel.php
-        class: 'App\Kernel'
-        env: test # When explicitly set, will override APP_ENV loaded from env_file file
-        debug: true  # When explicitly set, will override APP_DEBUG loaded from env_file file
-```
-
-Symfony 4 is automatically detected, based on the existence of default `src/Kernel.php` kernel file.
-
-If you did not migrate to new Symfony structure yet or you are using custom paths/naming; you need to configure `kernel.bootstrap` parameter, to enable default Symfony 4 configuration as shown in the example below:
-
-```
-FriendsOfBehat\SymfonyExtension:
-    # env_file: .env # loaded from the default configuration
-    kernel:
-        bootstrap: ~ # this enables default Symfony 4 configuration
-        path: app/AppKernel.php
-        # class: 'App\Kernel' # loaded from the default configuration
-        # env: test # loaded from the default configuration
-        # debug: true  # loaded from the default configuration
-```
-
-Of course, you can always change each of those settings.
