Hugo is a static web site generator. I use Hugo to make this page (see general->impress).
Caution I wouldn’t recommend this method if you want to upgrade hugo continuously.
Install TL;DR If you are Go-lang user, please go next section. Unless, I highly recommend you, who just want to use Hugo features (not Go), to install as follows (official says “Install Hugo from Tarball”).
curl -sSL https://github.com/gohugoio/hugo/releases/download/v0.97.3/hugo_0.97.3_Linux-64bit.tar.gz -o hugo.tar.gz tar xvfz hugo.
