IPFS or the InterPlanetary File System is a protocol and peer-to-peer network for storing and sharing data in a distributed file system. It's an amazing technology that allows people to share content and "repin" the content to strengthen the bandwith for the file.
DWEB domains have built-in support for linking directly to IPFS files via Decentraweb's IPFS gateway. A user who has the DWEB Resolver enabled can access the above IPFS file via a normal DWEB domain.

Once this is complete you will see two new additions on the page for setting (IPFS) "Content" and "DNS records". Click the blue edit button on the "Content" and past in a reference to your IPFS file. For example:
Save your changes and within 1-minute CONGRATS you should be able to see your IPFS file via your DWEB subdomain. If it doesn't display, ensure you are running the DWEB Resolver.
