# Quickstart

> Run the Nautilius product and choose the honest demo or live verification path.

Use the guided demo to evaluate the complete product story without credentials. Use the live workspace to inspect Coston2 state and attempt only operations whose prerequisites are available.

## Prerequisites

* Node.js and npm
* Go 1.25.1 or newer for the tee-node integration test
* A modern browser
* Foundry only when you want to run the Solidity suite

<Steps>
  <Step title="Install the web dependencies">
    From the repository root:

    ```bash theme={null}
    cd web
    npm ci
    ```
  </Step>

  <Step title="Start Nautilius">
    ```bash theme={null}
    npm run dev
    ```

    Open `http://localhost:3000` for the product page.
  </Step>

  <Step title="Choose a verification path">
    Open `/demo` for the labeled six-stage walkthrough. Open `/app` for the live Coston2 workspace.

    The live workspace reads verified configuration and stops when the FCC registry has no active TEE. It does not fall back to simulated production state.
  </Step>

  <Step title="Run the web gates">
    ```bash theme={null}
    npm test
    npx tsc --noEmit
    npm run lint
    npx next build --webpack
    ```
  </Step>
</Steps>

<Info>
  The web test suite binds a loopback port and starts the pinned tee-node decrypt harness. That test proves wire compatibility, not production attestation or hardware isolation.

Next, follow the [judge walkthrough](/start/judge-walkthrough) or reproduce the [complete local verification suite](/build/reproduce-locally).
