- How do I register for a hackathon listed here?
- Every listing here links back to the organizer's registration page — Devfolio, Devpost, HackerEarth, Luma and Unstop — and registration happens there, not on Jamao. Nothing is behind a login and no listing is paid placement. Running one? Claim your listing from its page, or add it free at jamao.in/create, and it stops being overwritten by the import.
