A getting started guide
One page covering the first useful loop, start to finish.
Docs
There is now a public getting started guide at quivergtm.dev/getting-started. It walks the whole loop in about thirty minutes: confirm the context Quiver drafted, add one piece of customer evidence, create a real campaign, run a focused session, save the work, and log what happened.
It is linked from the homepage and from the docs, and it is the first thing the welcome email points you at.
