You decide what Ari can reach. Start with your billing system (Stripe or Chargebee), then
add CRM, accounting, and document integrations as your workflows need them.

<Steps>
  <Step title="Open the control panel">
    Message Ari privately: `@Ari settings`. He sends you a link to the LedgerUp control
    panel; log in with your LedgerUp credentials.
  </Step>

  <Step title="Authorize the integration">
    Go to **Integrations**, choose the system, and authorize access through that
    system's own login. You choose the account and confirm the permissions being
    granted.
  </Step>

  <Step title="Verify it works">
    Back in Slack, ask a question only that system can answer:
    <SlackMessage><AriMention /> how many customers do I have in Stripe?</SlackMessage>
  </Step>
</Steps>
