I assume you already have a Hexo blog initialized.
cd <path-to-hexo-folder>/themes git clone https://github.com/artchen/hexo-theme-fact.git fact
Don't forget to modify
_config.yml under root directory of Hexo blog. Change theme to Fact.
Some configuration can be found in
_config.yml under the
cd <path-to-hexo-folder>/themes/fact git pull
If you do not use Typekit, here are the necessary steps to switch to other services:
layout/_partial/head.ejs, delete the lines that include the typekit library, then include necessary files from your choice of web fonts (eg: Google Font).
source/css/_sass/style.scss, change the font macros to your choices.
