[johnnymatthews]

The Websites on IPFS tutorial talks about linking up an ENS domain to a CID, but doesn't mention Handshake domains. A few hackathon participants have requested that it'd be nice to see a similar explanation for Handshake domains.

Tasks

• [ ] Explore Handshake domains to see if it's possible to link a CID to them.
• [ ] Create a new section in how-to/websites-on-ipfs/link-a-domain/ called Handshake.
• [ ] Add steps to link a CID to a Handshake domain.
