@micter59 thanks and congrats on your first Symfony Docs contribution 🎉

Please note that while merging I reword this a bit (see f9aaa15) to remove the example and link instead to the docs that fully explain this option.

@javiereguiluz Thanks ! The first one was a bit difficult for me, but maybe it'll get better with the next ones ;-D
