# Introduction (/learn)



Learn is a course, not a reference. Each chapter builds on the one before
it, and by the end you'll have done every core thing Xentr is for — not read
about it, done it.

## What you'll build [#what-youll-build]

Working through the chapters in order, you will:

* **Set up your access** — sign in, land in your organization, and (optionally) mint an API token.
* **Model a product** — define what you make, its production method, and the target rate every order is measured against.
* **Plan and run an order** — schedule a production order onto a machine, start it, and watch progress land live on the floor views.
* **Close it with quality data** — record good versus reject at closeout, so scrap shows up by product instead of in a month-end spreadsheet.
* **Staff the factory** — invite planners, technicians and QA with the right role each, least privilege by default.

That's the full loop: model → plan → run → close → staff. Everything else in
Xentr — OEE, reports, the wallboard, the copilot — feeds off the data you'll
create here.

## How to use this course [#how-to-use-this-course]

* **Do the chapters in order.** Each one assumes the last one's result exists.
* **Budget about 30 minutes** end to end. Every chapter leaves you with something working.
* You only need a browser. The API appears once, optionally, in the setup chapter — the whole loop works from the dashboard.

When you're done, [Next steps](/learn/next-steps) points into the deeper
guides and the API reference.
