Description
Do not specify the exact number of skaffold stages. The currently specified number does not agree with the diagram or subsequent table, and is likely to change.

I know. Nobody expects the Spanish Inquisition.

Amongst our stages are ...

Ha! Thanks for noticing. Definitely needs @nkubala's input because I'm not sure if we're counting the blue squares or all squares.

@briandealwis In addition to the initial diagram, which has 7+2 stages, there is also the table of Skaffold Pipeline stages at the bottom of the page, which has nine rows - but maybe Init shouldn't be counted.

By the way, elsewhere (api.md), the doc refers to the phases of the pipeline as build, deploy, and sync.

@joebowbeer lol nice catch :) to be honest our diagrams are getting stale and might need to be updated in the future. I wonder if we should just say multi-stage workflow so we don't have to keep updating that string?

[nkubala]

also worth mentioning that as a team we collectively agree our docs need lots of love - this is yet another item to add to the list of things to address

[joebowbeer]

@nkubala I applied your multi-stage suggestion.
