Why this is worth more than it costs
One thing you should know, because it shapes everything, and it's the reason this costs what it costs.
Hermes is moving fast. In the nine days around when I started this, the project shipped three major releases. The build I started on was v0.16.0; by the time you're reading this it's already old news, v0.17.0 and counting, and it moves briskly enough that a normal book would be out of date before the ink dried.
So this isn't a normal book. It's a living playbook. It carries a visible revision log, and it gets refreshed every four to six weeks. The parts most likely to drift... the exact buttons, the screen names, the install wizard... are exactly the parts I keep current. When the app changes, the playbook changes, and you get the update.
You already know this is true, by the way. You've had the app open. You've seen it update.
That's the whole reason the subscription exists, and I want to be plain about it. You're not paying for a snapshot of June 2026. You're paying for current. Every four to six weeks, when Hermes ships something new, you're the reader who already has the updated steps, and a growing library of new use cases, instead of the one squinting at a tutorial that no longer matches the screen in front of them.
A tool that changes weekly needs a guide that changes with it. That's the deal.
One honest comparison, because it matters: a guide like this competes with the consultant you're not hiring, the one who'd charge a few thousand dollars to sit with you for a few weeks. Eighty dollars to get there yourself, with the steps in hand and the updates included, is a different kind of deal.
