Symfony tutorial: Embed a Collection of Forms

WATCH THE VIDEO AT A HIGHER SPEED ITS MUCH BETTER.

Okay In this symfony 3 tutorial i went through how you can embed a collection of forms, which simply means including a form within a form if that makes any sense to you, and here's what this video covers basically:

Configuring your symfony application to use sqlite instead of mysql.
Using bootstrap as a theme for Twig templating engine.
Creating entities and relationships in Doctrine 2.
Creating forms that the user can interact with.
Javascript and jQuery which help us generate and remove forms dynamically.

There was a lot of editing on this video because debugging was taking so much time and i didn't want to make the video any longer.
