# Setup overview

> The four steps to go from zero to a working Synheart integration

To build with Synheart Core, complete these four steps in order. Standalone use of `synheart_wear`, `synheart_behavior`, or `synheart_session` only requires their package — skip ahead to the [Quickstart](/quickstart) for those tracks.

<Steps>
  <Step title="Install the CLI">
    `curl -fsSL https://synheart.sh/install | sh` — see [Install the CLI](/setup/install-cli).
  </Step>

  <Step title="Create a platform account">
    Synheart is invite-only. [Request access](https://synheart.ai/work-with-us), then sign up at [platform.synheart.ai](https://platform.synheart.ai). See [Create a platform account](/setup/create-account).
  </Step>

  <Step title="Authenticate the CLI">
    `synheart login` signs the CLI in via OAuth Device Flow. See [Authenticate the CLI](/setup/authenticate).
  </Step>

  <Step title="Install the runtime">
    `synheart install runtime` downloads the native HSI engine into your project. See [Install the runtime](/setup/install-runtime).
  </Step>
</Steps>

Once setup is complete, jump to the [Quickstart](/quickstart) to initialize a Core SDK and start receiving HSI updates.
