Great start!

Some ideas here:

• expand on the high level responsibilities of a kubo node:
  Managing swarm connections (including all the crypto handshakes), managing the blocks repo, exposing the rpc API, exposing a gateway http server, running a DHT server/client, handling bitswap transfer.
• touch on the recommended defaults for all of this (good opportunity to do a sweep if the baseline requirements are consistent for kubo)
• dive into some of the approaches for resource constrained environments: verified retrieval from gateways, delegated routing over HTTP (instead of a DHT), etc.

@2color wondering if we could crowdsource finishing up this PR.

What do you mean exactly by crowdsourcing this?

I'm happy to take a stab at this btw.
