If you view the Documentation page on a mobile phone, you will see that the left-hand navigation appears at the top and you have to scroll through it to get to the content. Right now, it's not so bad, but as we add more sections I think that is going to get too long and be a pain to have to scroll through.
So we have two possible solutions... we could either display all sections collapsed when the site is viewed on mobile, or we could move the entire nav into the hamburger menu. For the latter, there could be a divider after the Download button and the documentation nav would display underneath it (and maybe there could be some kind of header or styling to make it clear that this is a sub-nav for the Documentation page).
Do you guys have a preference?
