+# Mainly ~stolen~ inspired from the 'buku_run' script (https://github.com/carnager/buku_run/).
+# It is meant to be run as a modi (or script mode).
+# To get started, simply plop this script somewhere and run 'rofi -show buku -modi buku:<PATH>' and some of your personal options (e.g., custom keybindings, fullscreen, position).
+#
+# Dependencies (or at least the version by the time I made this):
+# * Buku v4.3
+# * GNU Bash v5.0.13
+# * Dunst v1.4.1 with libnotify
+# * Rofi v1.6.0
+# * jq v1.6
+
+# The cache location.
