    <h1>StateManager | @ethereumjs/statemanager</h1>
    Basic usage of this library in the browser (using <a href="https://github.com/vitejs/vite" target="_blank">Vite</a>)

    <h3>Run the Example</h3>
    <ol>
        <li>Go to the library root directory (packages/[LIBRARY_NAME]/)</li>
        <li>Build "dist" folder with: npm run build</li>
        <li>Start Vite development server with: npx vite</li>
        <li>Open the example URL in the browser (http://localhost:5173/examples/browser.html)</li>
        <li>Open the development console (e.g. Chrome Developer Tools)</li>
        <li>See example results and play with the code</li>
    </ol>

    <h3>Interactive CLI</h3>
    <ol>
        <li>Open the "Sources -> Page" tab in the Chrome Developer Tools</li>
        <li>Set a breakpoint within the original "browser.html" file (so not the one generated by Vite)</li>
        <li>Now you can use and play with the imports dynamically</li>
    </ol>
