Minima

It's Jekyll's default (and first) theme. It's what you get when you run jekyll new. Minima has been scaffolded by the jekyll new-theme command and therefore has all the necessary files and directories to have a new Jekyll site up and running with zero-configuration. From Minima v3 onwards, the base layout is named base.html instead of default.html to avoid confusing new users into assuming that name holds a special status. Users migrating from older versions with customized _layouts/default.html are advised to rename their copy to _layouts/base.html. Migrating users with additional customized layouts may either update front matter references to the former default.html layout or create a new default.html layout referencing the current base.html, whichever route is the easiest.
