## Getting Started

<Steps>
  <Step title="Create or Select a Project">
    Set up a new project or select an existing one. See [Organizations & Projects](/gateway/concepts/organizations-and-projects).
  </Step>

  <Step title="Configure the Connector">
    Enable the connector and set up a Connector Profile in your project. See [Setup Connector Profile](/gateway/quickstart#setup-connector-profile).

      <Card title="Connector Profile · No Authentication" href="/connectors/clinicaltrialsgov/guides/connector-profile/no-authentication" icon="https://stackone-logos.com/api/clinicaltrialsgov/filled/svg" horizontal>
        The ClinicalTrials.gov API v2 is fully public and read-only. No credentials, API key, or OAuth flow are required — simpl...
      </Card>
    </Columns>
  </Step>

  <Step title="Link an Account">
    Link an account [from the dashboard](/connect/managing-connectors/linking-accounts#link-from-the-dashboard) (or via [StackOne Hub](/embed/account-linking/overview)).

    See the guide for the authentication type chosen in the Connector Profile:

    </Columns>
  </Step>

  <Step title="Use Actions">
    Connect an AI platform to the linked account's actions. See [AI Platforms](/connect/ai-platforms/overview).

    Other ways to call actions are listed in [Protocols & SDKs](/connect/protocols-and-sdks).
