Base16 Builder is easy to use. All you have to do is supply a color scheme, template, and brightness (light or dark). Base16 Builder will use the information you provide to generate a theme and write it to stdout. Because Base16 Builder writes to stdout, it's possible to pipe the theme anywhere you like. In the above screencast, the theme is piped to a new file called "theme", but this could just as well have been a configuration file like ".Xresources".
