… (javiereguiluz)This PR was squashed before being merged into the 3.3 branch (closes#8273).Discussion----------Reworded the built-in web server articles for Symfony 3.3Thisfixes#8270.The current scenario for Symfony 3.3 is the worst possible: we don't have the web server by default (like in 3.2) ... and it's not easy to install it (like in 3.3+Flex or 4.0). That's why I propose to add a link in the main `setup.rst` article to the full explanation about installing and enabling the bundle.In 4.0, we can remove that link and simply say: run `symfony require web-server` and then, execute `./bin/console server:run`.Commits-------0cd417b Reworded the built-in web server articles for Symfony 3.3
