Loïc, thanks and congrats on your first Symfony Docs contribution 🎉

Note that while merging we did some rewords: see84634a2 I know it looks like we changed everything ... but we only reword it to match the style of the existing docs. The core of your original contribution remained, so thanks for it. We also added theversionadded directive.
