There are two 'code-along' style videos on the IPFS youtube page I found helpful

IPFS PubSub Demo: https://www.youtube.com/watch?v=Nv_Teb--1zg

Google Docs esque clone with CDRTs: https://www.youtube.com/watch?v=-kdx8rJd8rQ

Theres also a pubsub room example on the ipfs-shipyard github: https://github.com/ipfs-shipyard/ipfs-pubsub-room
