+## Script to get location of album art from cmus music player to use in conky.
+
+## Make sure to include this script in your .conkyrc and point conky to the symlinked image.
+## Note: As of now, this script links the image without the extension. This is due to .png files now being recognised.
+## Please update your .conkyrc to reflect the change.
+## You should position the image (with the -p option) close to the line where you execute the script,
+## to ensure that the output takes it's place if it isn't present.
+
+## Here is an example of what I put in my .conkyrc:
+## ${execi 4 /home/ab/scripts/cmus-conky-art.sh}
+## ${image /home/ab/conkyart -s 200x200 -p 4,470}
+ 
+## The CONKART variable below determines where the art will be symlinked to ('conkyart' is the actual symlinked image):
+
+CONKART=$( echo "$HOME/conkyart" )
