<p>SearXNG supports <em>external plugins</em> / there is no need to install one, SearXNG
runs out of the box. But to demonstrate; in the example below we install the
SearXNG plugins from <em>The Green Web Foundation</em> <a class="reference external" href="https://www.thegreenwebfoundation.org/news/searching-the-green-web-with-searx/">[ref]</a>:</p>

<h2>Plugin entry points<a class="headerlink" href="#plugin-entry-points" title="Permalink to this heading"></a></h2>
<p>Entry points (hooks) define when a plugin runs. Right now only three hooks are
implemented. So feel free to implement a hook if it fits the behaviour of your
plugin. A plugin doesnt need to implement all the hooks.</p>
