Do we want to mention that a sidecar is needed?

Do we want to mention that a sidecar is needed?

We should say that the sidecar is optional, but we could link to it (https://github.com/regen-network/cosmosd) and mention that it specifies a format for the Plan.Info field that will automatically download binaries: https://github.com/regen-network/cosmosd#auto-download

I like that @aaronc

Added a small section on sidecar process.
