Font Awesome 5 Icons not working on Bootstrap 4 : <p>I was trying to add the github (<code>class="fas fa-github"</code>) icon on a bootstrap dark button, but the button icon and text doesn't appear (the console shows nothing)</p>

<p>Code:</p>

<pre><code>&lt;div class="jumbotron"&gt;
    &lt;h1 class="display-4"&gt;Henrique Borges&lt;/h1&gt;
    &lt;p class="lead"&gt;Programador experiente e Web Designer.&lt;/p&gt;
    &lt;hr class="my-4"&gt;
    &lt;p&gt;It uses utility classes for typography and spacing to space content out within the larger container.&lt;/p&gt;
    &lt;p class="lead"&gt;
    &lt;a class="fas fa-github btn btn-dark btn-lg" href="#" role="button"&gt;Github&lt;/a&gt;
    &lt;/p&gt;
&lt;/div&gt;
</code></pre>

<p>I´ve already included both the BS and FA libraries:</p>

<pre><code>&lt;link rel="stylesheet" href="css/bootstrap.min.css"&gt;
&lt;script src="js/jquery-3.2.1.min.js"&gt;&lt;/script&gt;
&lt;script src="js/fontawesome-all.min.js"&gt;&lt;/script&gt;
</code></pre>
