## Best for

A dark rounded side panel with a canvas dot sphere animation behind ring step markers and Terms and Help buttons

## Agent notes

- `OnboardingSidebar` is forced dark and `DotSphere` paints its own `bgColor` and `dotColor` defaults, so restyle both for a light brand
- The Terms of Service and Help Center buttons in `OnboardingSidebar` have no `onClick` or link, so wire them to real pages
- `INDICATOR_CLASSNAME` and `SEPARATOR_COLOR_CLASSNAME` hardcode white ring and line colors, so they only read on the dark panel

## When not to use

- Account settings for returning users with vertical sidebar tabs for team and billing: use [Account & Team Settings](https://web.dev.reui.io/blocks/application/profile/profile-1.md) (`get_block("profile-1")`)
- A step rail that follows the app theme on the page canvas, with no dark side panel: use [Sidebar Stepper Wizard](https://web.dev.reui.io/blocks/application/onboarding/onboarding-2.md) (`get_block("onboarding-2")`)

## Install

```bash
npx shadcn@latest add @reui/onboarding-3
```

## About Onboarding blocks

### When to use

- A first-run setup after signup that collects profile, role, team size, goals and teammate invites
- Workspace creation shown as a full page, beside a product preview or in a modal over the app
- Developer tool signups that end by picking a coding agent and copying its CLI install commands

### When not to use

- A multi-step business task such as billing, vendor intake, a product listing or a transfer: use the [Wizard blocks](https://web.dev.reui.io/blocks/application/wizard.md)
- Only a progress indicator to place above step content you already built: use [Stepper](https://web.dev.reui.io/components/stepper.md) (`get_component("stepper")`)
- A purchase flow with shipping, payment and an order summary beside the steps: use the [Checkout blocks](https://web.dev.reui.io/blocks/ecommerce/checkout.md)

### Agent notes

- `completeOnboarding` only waits on a `window.setTimeout` before the ready screen; post the collected answers to your API there
- Replace `ONBOARDING_STEPS`, `ROLE_OPTIONS`, `GOAL_OPTIONS` and `DEFAULT_INVITES` in data.tsx; the step order and titles come from `ONBOARDING_STEPS`
- The timezone `Combobox` over `TIMEZONE_GROUPS` takes no `value` or `onValueChange`, so the picked zone never reaches component state

Every ReUI item has a twin like this one; the index is https://web.dev.reui.io/llms.txt. Agents with the ReUI MCP (https://web.dev.reui.io/docs/mcp) get the same guidance from the getters named above.
