Yes 100% agree. Did some work to include more of the inputs and outputs in the Quickstart Guide in #32 but we will need another ticket to enumerate this with all of the flags not just the required params and expected output.

Also, I think in the future we should split this up into a CLI Reference and a Workflows section, but in #32 I at least labeled the section as CLI reference so that it's closer to what we wanna work towards
