 ## Introduction
+
 [zend-phpdi-config](https://packagist.org/packages/elie29/zend-phpdi-config) acts as a bridge to configure a PSR-11 compatible [PHP-DI](http://php-di.org) container using service manager configuration.
 It can be used with [Laminas](https://getlaminas.org/) and [Mezzio](https://docs.mezzio.dev/) starting from v6.0.0

 ## CLI command to add a new autowire entry
+
 ![Configuration image](./config-add-entry.png)
 
 The cli command `add-autowires-entry` creates the configuration file if it doesn't exist otherwise it adds the entry
 to the autowires key.

 ## Switching back to another container
 
 To switch back to another container is very easy:
-  1. Create your factories with `__invoke` function
-  2. Replace `autowires` key in ConfigProvider by `factories` key, then for each class name attach its correspondent factory.

 ## PSR 11 and Interop\Container\ContainerInterface
