Hacktoberfest, an annual event in October in collaboration with DigitalOcean, celebrates open source software by encouraging global participation in contributing to projects, ranging from documentation enhancements to feature development. In its fourth iteration, it has seen significant engagement, with over 90,000 pull requests made by contributors from 114 countries in the previous year. The event not only fosters community engagement but also helps first-time contributors transition into regular contributors and maintainers. Participants are motivated by the opportunity to make impactful contributions and the incentive of receiving a limited-edition t-shirt for completing four valid pull requests. The event encourages contributions by searching for projects with the 'hacktoberfest' label and promotes sharing experiences on social media using the #hacktoberfest hashtag.
