@colin-axner right now IBC docs are shown inside a section on the left on docs.cosmos.network. Do we want to keep that, or does IBC have a plan to have its own docs page? Maybe we could just delete the docs/ibc folder from the SDK to avoid these copy/paste PRs?

The plan is to eventually create a docs subdomain for ibc-go, but in the short term we should maintain the docs in the SDK. A lot of folks are looking into this documentation since transfer enablement on a lot of chains is imminent. Once there is a docs site up for ibc-go we can remove the docs from the SDK
