Be sure to have io.js installed. (Node.js will do if you feel like rockin' in 2013 style.)

Run npm install in the project root. This will install some build tools we use.

Run npm run watch to start a watcher that will compile things in place. You can then view the site by simply opening index.html.

Run npm run build to do a local build into the out/ directory. You can then preview the site at out/index.html. This should usually be the same as just index.html, but it is good to check before committing, since the build process is slightly more complicated than the in-place watch process.

Stylus is used for styling.

Handlebars is used for templating. index.hbs is minimally templated, mostly delegating to the partials in templates/. Those pull their data from data/. The logic that ties them all together is in build/templater.js.

Gulp is used for a build/watch system. This is abstracted behind npm tasks though (npm run watch, npm run build).

Traceur is used to write ES2015 code instead of boring-old-JavaScript, for the build code at least.

Travis is used to build and deploy the website to gh-pages on each push, per this guide.

The site is intended to be responsive, which we accomplish with per-device stylesheets and media queries in the HTML.

While editing you should be using an EditorConfig plugin for your text editor to enforce a few basic stylistic things.

We are trying to maintain a reasonable HTML document outline (so, don't use <section> as if it were <div>). To preview the document outline, use the HTML 5 Outliner tool; here's a direct link to the outline for the current version.
