(function () {

    'use strict';

    var x, header, article, link,
        container = document.querySelector('section.container'),
        sections = container.getElementsByTagName('article'),
        length = sections.length,
        items = [],
        tocEl = document.getElementById('toc');

    // parse each section, extract H1 title and push to 'toc' array
    if (sections) {
        for (x = 0; x < length; x+=1) {
            article = sections[x];
            if (article) {
                header = article.getElementsByTagName('h1')[0].innerText;
                link = article.querySelector('a.permalink').href;
                items.push('<li><a href="' + link + '">' + header + '</a></li>');
            }
        }
    }

    // generate table of contents markup
    tocEl.innerHTML = '<ul>' + items.join('') + '</ul>';

}());

I think you will have to do it manually unless Gist Markup allows for TOC generation. Something I'm not aware of today.

Ok!
Thanks for your time mate.
