Challenges we ran into

The major challenge we ran into was implementing the functionality to share the note via IPFS. We explored over five different IPFS "pinning" services, but to no avail. One error here, another error there. And we were doing all of this for the first time. We settled on having to download an extension and toggling one setting in it.
We made a separate video about that: https://vimeo.com/746268245
