title: use bootstrap icons with npm
body: <p>When I use any JS-module with NPM I include it into my .js file with <code>require(&quot;&quot;)</code>. How can I do the same with <a href="https://icons.getbootstrap.com/" rel="noreferrer">bootstrap icons</a> and include them into .html?
  Their official <a href="https://icons.getbootstrap.com/#usage" rel="noreferrer">docs</a>  and <a href="https://www.npmjs.com/package/bootstrap-icons" rel="noreferrer">npm</a> wasn't clear enough for me.</p>
  <p>I don't use bootstrap in my project, only few icons, is it enough to have only this package?</p>
  <pre><code>npm install bootstrap-icons
  </code></pre>
  <p>Are bootstrap icons really free? Should you mention them in the project?</p>
