About This Article
The Kotlin Foundation wanted to make it easier for newcomers to contribute to open-source Kotlin projects. Most people didn't know how to get started or what steps to take from joining a project through to getting their code merged.
The Kotlin Ecosystem Mentorship Program matches mentees with experienced maintainers who walk them through the contribution process step by step. Participants get Kotlin-branded swag and a chance to win a trip to KotlinConf 2026.
The program gives first-time contributors a clear path forward. With limited mentor-mentee pairs, it helps grow the Kotlin community by making people feel supported when they make their first real open-source contribution.
