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!
