  <Steps>
    <Step title="Sign up and get your API key">
      Create an account at [sendook.com](https://sendook.com) and generate your API key from the dashboard.

      <Note>
        Your API key is used to authenticate all requests to the Sendook API. Keep it secure and never share it publicly.
      </Note>
    </Step>

    <Step title="Install the SDK or use the REST API">
      Choose your preferred integration method:

      <CodeGroup>
        ```bash npm theme={null}
        npm install @sendook/node
        ```

        ```bash yarn theme={null}
        yarn add @sendook/node
        ```

        ```bash pnpm theme={null}
        pnpm add @sendook/node
        ```
      </CodeGroup>

      Or use the REST API directly with any HTTP client.
    </Step>

    <Step title="Create your first inbox and send an email">
      Start sending and receiving emails programmatically:

      <Tabs>
        <Tab title="TypeScript SDK">
          ```typescript theme={null}
          import Sendook from "@sendook/node";

          const client = new Sendook("your_api_key");

          // Create an inbox
          const inbox = await client.inbox.create({
            name: "support",
            email: "support@sendook.com"
          });

          // Send an email
          await client.inbox.message.send({
            inboxId: inbox.id,
            to: ["user@example.com"],
            subject: "Welcome to Sendook!",
            text: "Thanks for signing up.",
            html: "<p>Thanks for signing up.</p>"
          });
          ```
        </Tab>

        <Tab title="cURL">
          ```bash theme={null}
          # Create an inbox
          curl -X POST https://api.sendook.com/v1/inboxes \
            -H "Authorization: Bearer your_api_key" \
            -H "Content-Type: application/json" \
            -d '{
              "name": "support",
              "email": "support@sendook.com"
            }'

          # Send an email
          curl -X POST https://api.sendook.com/v1/inboxes/{inbox_id}/messages/send \
            -H "Authorization: Bearer your_api_key" \
            -H "Content-Type: application/json" \
            -d '{
              "to": ["user@example.com"],
              "subject": "Welcome to Sendook!",
              "text": "Thanks for signing up.",
              "html": "<p>Thanks for signing up.</p>"
            }'
          ```
        </Tab>
      </Tabs>
    </Step>

    <Step title="Set up webhooks to receive emails">
      Configure webhooks to handle incoming emails automatically:

      ```typescript theme={null}
      await client.webhook.create({
        url: "https://your-app.com/webhooks/email",
        events: ["message.received"]
      });
      ```

      Your webhook will receive parsed email data whenever a message arrives in your inbox.
