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.

 * 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:
 * Wikimedia Developer Portal
 * Learn about Phabricator
 * Information for new developers
 * Basic skills needed to contribute to development of MediaWiki core and MediaWiki extensions
 * An overview of the MediaWiki Action API
 * The Wikidata Query Service (WDQS) provides a way for tools to access Wikidata data
