Thanks @shaneutt, looks good to me, I will leave the final tag to @kfswain

[kfswain]

Yeah! I think this looks great also, I'll apply all approval labels + a hold to give a chance to take a look at the nit/submit on your own terms. But if you're ready to merge just pull the hold off. Thanks for taking the time and care to enrich our landing page! Laying some ground definitions makes a lot of sense.

I would unhold and ship it, but will leave it as I don't want to stomp on any discussion being had.

Thanks @shaneutt!!

@shaneutt consider leveraging this doc which provides good definitions for several applicable terms.

Could you help me please to better understand how precisely you're hoping for this to be incorporated? In particular, suggestion comments with explicit suggestions about changes would be ideal because they don't leave any room for misinterpretation.

[danehans]

@shaneutt IMHO, we should consider leveraging each term and associated definition from https://cloud.google.com/kubernetes-engine/docs/concepts/machine-learning/inference#terminology.

Github seems to be unable to track my branch at the moment, after my fork moved, so I'm going to re-create.
