+## Configuration
+
+The theme behaves similar to vim's airline/powerline plugins. It needs a
+[powerline font][font]. Although it works with emacs mode, it's more powerful
+with vi mode. In order to enable vi mode, put the following lines into
+`$HOME/.config/fish/config.fish` before `set fish_path $HOME/.oh-my-fish`:
+
+```
+set -e fish_key_bindings
+set -U fish_key_bindings fish_vi_key_bindings
+```
