+# CountDown.sh
+A simple script to countdown from a certain number to zero. I made it so that
+I can easily delay the playing time of songs by a few seconds before I play it
+on the guitar.
+
+```
+USAGE:
+	countdown.sh <sec>
+
+OPTIONS:
+	<sec>      number to countdown from [default: 5]
+
+EXAMPLE:
+	Countdown from 7 and then play Scott Stapp's "Last Hallelujah"
+		./countdown 7 ; mpv 12_-_Last_Hallelujah.flac
+```
