+# This script is Public Domain.
+#
+# A basic screen recording script based on wf-recorder for sway,
+# required executables:
+# wf-recorder - for the actual screen recording
+# jq - to parse JSON
+# slurp - to select a screen area
+# notify-send - for notification functionality
+#
+# Loosely based on:
+# https://gist.github.com/ugursogukpinar/f390d9f4c829fb1b05fc74a12dd482bb
+#
+# Usage:
+# screenrecord.sh - record whole screen
+# screenrecord.sh -s - record screen area
+# screenrecord.sh -w - record window
+# screenrecord.sh -t - (may be used with any other option) if screenrecording
+#                      is currently active, toggle it off and no recording takes
+#                      place
