FAQ

Do I need a team to join?
Not necessarily. You’re welcome to join solo, form a team on Discord or connect with others during team formation at the hackathon.
If you join as a team, please just make sure everyone registers individually to get access to the venue.

Do I need to prepare?
Get a head start with the Restack quickstart.
To join the competition, you’ll need to use Restack. So getting set up early will help you make the most of the weekend.

I’m not technical. Can I still join?
This is a tech hackathon, and most participants will be coding.
That said, we welcome technical product managers and other roles who contribute to a strong team. When in doubt, just contact us.

You can also join as volunteer.
