Load the module after loading highlight.js. You'll use the minified version found in the dist directory. This module is just a CDN build of the language, so it will register itself as the Javascript is loaded.
<!DOCTYPE html>
<head>
<link rel="stylesheet" href="monokai-sublime.min.css">
<script src="highlight.min.js"></script>
<script type="text/javascript" src="c3.min.js"></script>
<script>hljs.highlightAll();</script>

<body>
<pre><code class="c3">
import std::io;
fn void main()
{
io::printfn("hello, world");
}
</code></pre>

</html>If you're using Node / Webpack / Rollup / Browserify, etc, simply require the language module, then register it with Highlight.js.
var hljs = require('highlight.js');
var hljsC3 = require('highlightjs-c3');
hljs.registerLanguage("c3", hljsC3);
hljs.highlightAll();- The highlight.js GitHub project: https://github.com/highlightjs/highlight.js
