You are browsing the Symfony 4 documentation, which changes significantly from Symfony 3.x. If your app doesn't use Symfony 4 yet, browse the Symfony 3.4 documentation.
Reading the contributing is already a great way to get started on becoming a Symfony contributor. However, sometimes it might still seem overwhelming - contributing can be complex! For this purpose we created a dedicated Symfony Slack channel called #mentoring to connect new contributors to long-time contributors. This is a great way to get one-on-one advice on the entire process. These long-time contributors do really want to help new contributors - so feel free to ask anything!
