Please read the
<a href="https://github.com/JohnXLivingston/peertube-plugin-livechat/blob/main/README.md" target="_blank">
  documentation
</a>
before trying to use this plugin.<br>
There is 3 way to use it:
<ul>
  <li>
    By installing the Prosoxy XMPP server package on your server,
    and using the «builtin Prosody XMPP Server» feature.
    <a

      target="_blank"
    >
      See Documentation
    </a>
  </li>
  <li>
    By using an existing XMPP server, with anonymous authentication and rooms enabled.

    </a>
  </li>
  <li>
    By using any external webchat that can be included in an iframe.
