+#### Code injection
+
+You can inject any html code to every page's document head or right above the closing body tag. This makes it easier to add any html meta data, custom css/js, dns-prefetch etc. To do this you simplely need to creat a file at site's `layouts/partials/extra-head.html` or `layouts/partials/extra-foot.html`, code inside will be injected to every page.
