My personal opinion: the second button after “Download” should point to “Learn” rather than directly to the “Documentation”. Reasons:
- interested users know how to go there already from the menu on the top (or directly typing docs.julialang.org/…)
- for “explorer” visitors it may be too intimidating… that documenter-built page is at odds with the design of the rest of the site… better that explorers reach it after they digest a bit of the site, e.g. from “Learn” and then “getting started”…
