As it is often said in various designer forums, please avoid pure white (#FFFFFF) on black (here #111111), as it makes the text glow for the human eyes (therefore making it unreadable for long text). Instead, try to lower a bit the contrast on the text color.
Also, the dispositions for the buttons at the beginning (GitHub, NPM, ...) are not adjusted correctly for keyboard navigation (each button requires two tabs).
Appart from that, I do like a minimalist stylesheet, so I will also recommend Tufte CSS [0] for readers.
