The Simplicissimus theme is just HTML. Nothing else. No CSS. No fonts. Just plain HTML. Nothing more, noting less.
Enter your project (assuming your project is called project):
cd project
mkdir themes
export URL=https://github.com/ckuelker/pankyll-theme-simplicissimus.git
git clone --recursive $URL
If your project is already a git repository:
cd project
mkdir themes
export URL=https://github.com/ckuelker/pankyll-theme-simplicissimus.git
git submodule add -b master $URL themes//pankyll-theme-simplicissimus
git submodule init
Some features of other themes are as of now deliberately not supported:
Some of the features are defined in the configuration feature section. The presence of this feature in the configuration is just to speed up Pankyll and setting them to True
will make Pankyll run longer, but not create the links or other snippets to include this features.
