This had already been done locally on the Portuguese wikipedia, now it is implemented directly in core.

Events and resources for newcomers

The Wikimedia Hackathon in May 2023 is focused on technical contributors who are already autonomous with finding and working on projects. Therefore, the program items dedicated to newcomers will be limited, and the participants are expected to find their way in the technical environment of the Wikimedia projects.

If you’re new to the Wikimedia project and/or to development, here’s a list of events you could consider joining instead:

Small Wiki Toolkits workshops
WikiConference India in March 2023 will have a hackathon/technical track
Pre-hackathon events organized by local communities
Wikimania 2023 is an event that everyone can join and that will include technical sessions

You can also check this list of resources to get on board on technical contribution:
