The first step can change a lot.
My journey in Open Source started with CodeIN Community. My first ever contribution here stirred such an interest in Open Source.
Community based learning is just awesome. Mentors are really helpful and helped a lot during my coding journey.
NEW CHAPTER. SAME COMMUNITY.
Built on every contribution

The website has evolved. The people, the history, and the work that brought us here are part of everything we build next.
