  <Steps>
    <Step title="Select the Right Environment">
      <div data-guide-step data-guide-scopes="" data-guide-display-scopes-list="">
        <p>When connecting Checkr to StackOne, you'll be asked to select an environment.</p>

        <ul>
          <li><strong>Production</strong> — Use for real background checks with actual candidate data. Requires account approval from Checkr.</li>
          <li><strong>Staging</strong> — Use for development and testing with fake data. Free to use, no approval required.</li>
          <li>Staging environment uses a separate base URL (api.checkr-staging.com)</li>
          <li>You can switch environments later by creating a new connection</li>
