Translations:New Template System in LS3.x/6/en

We will not detail here how Twig works. It’s kind of very simplified PHP that offers a high level of security thanks to the “sandbox” system (we’ll see that in more detail in the part about the Theme Engine Core code). If you already know PHP, it will be extremely easy for you to master. If you don’t know PHP, it still should be pretty easy to learn. Please, have a look to the Twig 1.X documentation: https://twig.symfony.com/
