+# wayar-dwl.sh - display dwl tags, layout, and active title
+#   Based heavily upon this script by user "novakane" (Hugo Machet) used to do the same for yambar
+#   https://codeberg.org/novakane/yambar/src/branch/master/examples/scripts/dwl-tags.sh
+#
+# USAGE: waybar-dwl.sh MONITOR COMPONENT
+#        "COMPONENT" is an integer representing a dwl tag OR "layout" OR "title"
+#
+# REQUIREMENTS:
+#  - inotifywait ( 'inotify-tools' on arch )
+#  - Launch dwl with `dwl > ~.cache/dwltags` or change $fname
+#
+# Now the fun part
+#
+### Example ~/.config/waybar/config
+#
+# {
+#   "modules-left": ["custom/dwl_tag#0", "custom/dwl_tag#1", "custom/dwl_tag#2", "custom/dwl_tag#3", "custom/dwl_tag#4", "custom/dwl_tag#5", "custom/dwl_layout", "custom/dwl_title"],
+#   // The empty '' argument used in the following "exec": fields works for single-monitor setups
+#   // For multi-monitor setups, see https://github.com/Alexays/Waybar/wiki/Configuration
