      <h2>How it works</h2>
      <p>
        ESP Web Tools works by combining
        <a
          href="https://developer.mozilla.org/en-US/docs/Web/API/Web_Serial_API"
          >Web Serial</a
        >, <a href="https://www.improv-wifi.com/">Improv Wi-Fi</a> (optional),
        and a manifest which describes the firmware. ESP Web Tools detects the
        chipset of the connected ESP device and automatically selects the right
        firmware variant from the manifest.
      </p>
      <p>
        Web Serial is available in Google Chrome and Microsoft Edge
        browsers<span class="not-supported-i hidden">
          (but not on your iOS device)</span
        >. Android support should be possible but has not been implemented yet.
      </p>

      <h3 id="improv">Configuring Wi-Fi</h3>
      <p>
        ESP Web Tools supports the
        <a href="https://www.improv-wifi.com/serial"
          >Improv Wi-Fi serial standard</a
        >. This is an open standard to allow configuring Wi-Fi via the serial
        port.
      </p>
      <p>
        If the firmware supports Improv, a user will be asked to connect the
        device to the network after installing the firmware. Once connected, the
        device can send the user to a URL to finish configuration. For example,
        this can be a link to the device's IP address where it serves a local
        UI.
      </p>
      <p>
        At any time in the future a user can use ESP Web Tools to find the
        device link or to reconfigure the Wi-Fi settings without doing a
        reinstall.
      </p>

      <h2 id="add-website">Adding ESP Web Tools to your website</h2>
      <p>
        To add this to your own website, you need to include the ESP Web Tools
        JavaScript files on your website, create a manifest file and add the ESP
        Web Tools button HTML.
      </p>
      <p>
        You can import the JavaScript files directly from the unpkg CDN or
        <a href="https://unpkg.com/browse/esp-web-tools/dist/web/"
          >download the files</a
        >
        and put them on your website.
      </p>
      <pre>
&lt;script
  type="module"
  src="https://unpkg.com/esp-web-tools@7.2.0/dist/web/install-button.js?module"
>&lt;/script></pre
      >
      <p>
        Find a place on your page where you want the button to appear and
        include the following bit of HTML. Update the
        <code>manifest</code> attribute to point at your manifest file.
      </p>
      <pre>
&lt;esp-web-install-button
  manifest="/static/firmware_build/manifest.json"
>&lt;/esp-web-install-button></pre
      >
      <p>
        ESP Web Tools requires that your website is served over
        <code>https://</code> to work. This is a Web Serial security
        requirement.
      </p>
      <p>
        If your manifest or the firmware files are hosted on another server,
        make sure you configure
        <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS"
          >the CORS-headers</a
        >
        such that your website is allowed to fetch those files by adding the
        header
        <code
          >Access-Control-Allow-Origin: https://domain-of-your-website.com</code
        >.
      </p>

      <p>
        ESP Web Tools can also be integrated in your projects by installing it
        <a href="https://www.npmjs.com/package/esp-web-tools">via NPM</a>.
      </p>
      <h3 id="manifest">Creating your manifest</h3>
      <p>
        Manifests describe the firmware that you want to offer the user to
        install. It allows specifying different builds for the different types
        of ESP devices. Current supported chip families are
        <code>ESP8266</code>, <code>ESP32</code>, <code>ESP32-C3</code>,
        <code>ESP32-S2</code> and <code>ESP32-S3</code>. The correct build will
        be automatically selected based on the type of the connected ESP device.
      </p>
      <pre>
{
  "name": "ESPHome",
  "version": "2021.11.0",
  "home_assistant_domain": "esphome",
  "new_install_prompt_erase": false,
  "builds": [
    {
      "chipFamily": "ESP32",
      "parts": [
        { "path": "bootloader.bin", "offset": 4096 },
        { "path": "partitions.bin", "offset": 32768 },
        { "path": "ota.bin", "offset": 57344 },
        { "path": "firmware.bin", "offset": 65536 }
      ]
    },
    {
      "chipFamily": "ESP8266",
      "parts": [
        { "path": "esp8266.bin", "offset": 0 }
      ]
    }
  ]
}</pre
      >
      <p>
        Each build contains a list of parts to be installed to the ESP device.
        Each part consists of a path to the file and an offset on the flash
        where it should be installed. Part paths are resolved relative to the
        path of the manifest, but can also be URLs to other hosts.
      </p>
      <p>
        If your firmware is supported by Home Assistant, you can add the
        optional key <code>home_assistant_domain</code>. If present, ESP Web
        Tools will link the user to add this device to Home Assistant.
      </p>
      <p>
        By default a new installation will erase all data before installation.
        If you want to leave this choice to the user, set the optional manifest
        key
        <code>new_install_prompt_erase</code> to <code>true</code>. ESP Web
        Tools offers users a new installation if it is unable to detect the
        current firmware of the device (via Improv Serial) or if the detected
        firmware does not match the name specififed in the manifest.
      </p>
      <p>
        When a firmware is first installed on a device, it might need to do some
        time consuming tasks like initializing the file system. By default ESP
        Web Tools will wait 10 seconds to receive an Improv Serial response to
        indicate that the boot is completed. You can increase this timeout by
        setting the optional manifest key
        <code>new_install_improv_wait_time</code> to the number of seconds to
        wait. Set to <code>0</code> to disable Improv Serial detection.
      </p>

      <h3 id="customize">Customizing the look and feel</h3>
      <p>
        You can change the colors of the default UI elements with CSS custom
        properties (variables), the following variables are available:
      </p>
      <ul>
        <li><code>--esp-tools-button-color</code></li>
        <li><code>--esp-tools-button-text-color</code></li>
      </ul>
      <p>There are also some attributes that can be used for styling:</p>
      <table>
        <tr>
          <td><code>install-supported</code></td>
          <td>Added if installing firmware is supported</td>
        </tr>
        <tr>
          <td>
            <code>install-unsupported</code>
          </td>
          <td>Added if installing firmware is not supported</td>
        </tr>
      </table>
      <h4>Replace the button and message with a custom one</h4>
      <p>
        You can replace both the activation button and the message that is shown
        when the user uses an unsupported browser or non-secure context with
        your own elements. This can be done using the <code>activate</code>,
        <code>unsupported</code> and <code>not-allowed</code> slots:
      </p>
      <pre>
&lt;esp-web-install-button
  manifest="/static/firmware_build/manifest.json"
>
  &lt;button slot="activate">Custom install button&lt;/button>
  &lt;span slot="unsupported">Ah snap, your browser doesn't work!&lt;/span>
  &lt;span slot="not-allowed">Ah snap, you are not allowed to use this on HTTP!&lt;/span>
