If there's one documentation that I hate with my gut, that is GCP documentation. Like wtf is going on there. Just to give you an example of how horrible it is, just check their Vision documentation: https://cloud.google.com/vision/docs/

They have quick starts, tutorials and how-to-guides. How are even those things conceptually different at all?. And their reference is just a list of their methods like if I knew out of the box how to use your API. Like, what the heck. Just tell me how to talk to your API in simple terms. How hard is it?

"To use the CGP vision API there are two ways to authenticate and connect. 1) REST 2) SDKS" and then just explain to me how to do it simply.

Don't ramble like if this was the fucking Iliad. Go straight to the point and organize your information better.
