It is based on hugo-theme-cleanwhite
I just do some customization for search.
And it can be used for my git submodule.
git submodule add https://github.com/zoushuyou/hugo-theme-shuyou.git themes/shuyou
git submodule update --remote --merge
git submodule deinit -f -- themes/shuyou
rm -rf .git/modules/themes/shuyou
git rm -f themes/shuyou
