# Guides

> Worked, end-to-end tutorials — real code, and the mistakes marked.

Each of these takes one job from nothing to working. They include the failure
cases, because those are the ones that cost money.

## Set up

<CardGroup cols={2}>
  <Card title="Cut the &#x22;I don't know&#x22; answers" icon="magnifying-glass" href="/guides/reduce-i-dont-know">
    A weekly half hour with the gaps report. The highest-return loop in the
    product, and most teams never open it.
  </Card>

  <Card title="Serve customers in their own language" icon="language" href="/guides/multilingual">
    One knowledge base, 37 languages — and why templates are the part that needs
    real work.
  </Card>

  <Card title="Make your agent sound right on the phone" icon="waveform-lines" href="/guides/how-your-agent-sounds">
    Why a reply that reads well can sound wrong out loud, and the handful of
    changes that fix it.
  </Card>
</CardGroup>

## Answer the phone

<CardGroup cols={2}>
  <Card title="Take bookings over the phone" icon="calendar-check" href="/guides/phone-bookings">
    A clinic line that asks for four details one at a time and reads the whole
    booking back — with the questions to try before you print the number.
  </Card>
</CardGroup>

## Connect your systems

<CardGroup cols={2}>
  <Card title="Answer &#x22;where is my order?&#x22;" icon="box" href="/guides/order-status">
    Your API, one action, and an agent that will not confirm an order to a
    stranger.
  </Card>

  <Card title="Recognise signed-in customers (Next.js)" icon="user-check" href="/guides/nextjs-identity">
    A complete App Router implementation, with the secret staying on the server.
  </Card>
</CardGroup>

## Reach out

<CardGroup cols={2}>
  <Card title="Send your first campaign" icon="paper-plane" href="/guides/first-campaign">
    Start to finish, with the expensive mistakes marked.
  </Card>

  <Card title="Recover abandoned carts" icon="cart-shopping" href="/guides/abandoned-cart">
    An event, a two-step sequence, and messages that stop when they buy.
  </Card>
</CardGroup>

## In what order?

If you are new, this sequence wastes the least time:

<Steps>
  <Step title="Get it answering">
    [Quickstart](/quickstart), then run [the gaps
    loop](/guides/reduce-i-dont-know) once. You will learn more about your own
    customers in half an hour than in a week of planning.
  </Step>

  <Step title="Make it useful">
    [Order status](/guides/order-status) — the point where an agent stops being
    a search box with manners.
  </Step>

  <Step title="Make it personal">
    [Signed-in customers](/guides/nextjs-identity). Everything downstream gets
    better once the agent knows who it is talking to.
  </Step>

  <Step title="Then reach out">
    [Broadcasts](/guides/first-campaign) and
    [sequences](/guides/abandoned-cart) last. Outbound to people your agent
    cannot yet help well is a way to spend money on disappointing customers.
