Configure the viewport

Your page does not have a viewport specified. This causes mobile devices to render your page as it would appear on a desktop browser, scaling it down to fit on a mobile screen. Configure a viewport to allow your page to render properly on all devices.
Use legible font sizes

The following text on your page renders in a way that may be difficult for some of your visitors to read. Use legible font sizes to provide a better user experience.

Eliminate render-blocking JavaScript and CSS in above-the-fold content

Your page has 2 blocking script resources and 1 blocking CSS resources. This causes a delay in rendering your page.

https://pages.github.com/js/application.js
Optimize CSS Delivery of the following:

Leverage browser caching

Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
Leverage browser caching for the following cacheable resources:
https://pages.github.com/css/octicons.woff (10 minutes)
https://pages.github.com/css/pages.css (10 minutes)
https://pages.github.com/images/code-editor@2x.png (10 minutes)
https://pages.github.com/images/commit-edits@2x.png (10 minutes)

Prioritize visible content

Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.
The entire HTML response was not sufficient to render the above-the-fold content. This usually indicates that additional resources, loaded after HTML parsing, were required to render above-the-fold content. Prioritize visible content that is needed for rendering above-the-fold by including it directly in the HTML response.
Only about 33% of the final above-the-fold content could be rendered with the full HTML response.
