How to Deploy a Symfony Application page needs updating for 4.x

[MicWit]

The page How to Deploy a Symfony Application (https://symfony.com/doc/current/deployment.html) needs someone familiar with Symfony 4.x to look through and see what needs to be changed. Some of the things I can see are:

• Instructions for Assetic (that now won't even load with Symfony 4) should be for webpack encore
• Is SYMFONY_ENV=prod used anymore or is it just APP_ENV=prod now?

I am only just starting into Symfony 4 (which is how I found this) so can't update it myself, and am looking how I will be deploying my app to production with Symfony 4.
