+----------
+
+In some distributions, Terminess Powerline is ignored by default and must be explicitly allowed. A fontconfig file is provided which enables it. Copy this file from the fontconfig directory to your home folder under `~/.config/fontconfig/conf.d` (create it if it doesn't exist) and re-run `fc-cache -vf`.
