        <h1>Title Article</h1>
        <p>Written by Foo.</p>
    </header>
    <nav>
        <ul>
            <li><a href="#section1" target="_parent">First Section</a></li>
            <li><a href="#section2" target="_parent">Second Section</a></li>
            ...more...
        </ul>
    </nav>
    <div>
        <section id="section1">
            <h1>First Section</h1>
            <p>...more...</p>
        </section>
        <section id="section2">

Creation

The table of content can be added to the HTML page at:

creation time
or at load time via a javascript library (example: Tocbot)

At load time, the library or a search engine would get/extract the table of content data from the outline.

Check

To check that your Table of Content is the same than the one that would view a library or a search engine, you can check your outline
