# What are you building?

> Pick a goal and follow a guided path. The sidebar then shows only the steps for that goal.

Pick the goal that matches what you build. Each card opens a guided path.
When you pick a card, the **sidebar switches** to only the steps for that
goal. Follow the steps from top to bottom. Use **Next** at the bottom of
each page. To go back to the full reference at any time, open the
**Explore all docs** menu at the top of the sidebar.

  - **[Build a Voice Agent](/paths/voice-agent)** — Build an AI voice agent for the phone or the browser. This path covers
    the quickstart, models, turn detection, tool calling, telephony, and
    going live.
  - **[Build a Contact Center](/paths/contact-center)** — Put AI **and** human agents on one queue. This path covers trunks and
    numbers, IVR flows, ACD, CTI, warm handoff, and live dashboards.
  - **[Add Realtime & Chat](/paths/realtime-chat)** — Add Pusher-compatible realtime channels and an embeddable chat widget
    to your web app. To migrate, change one URL or add a `<script>` tag.

> **NOTE:**
> To browse the full reference, open **Explore all docs** at the top of the
>   sidebar. It contains every product, SDK, and API. The guided paths are
>   curated routes through those same pages.
