I want to customize the "This site is open source. Improve this page." footer and add a header and footer of my own.
I've found Customizing CSS and HTML in your Jekyll theme and
could make the CSS part work using a /assets/css/style.css
file.
But I can't make the /_layouts/
& default.html
part work, I think it may be because I have not chosen a "theme" (actually I think themes will spoil my minimalist design).
