 A very simple tool to upload files to the zfh.so file hosting
 
-	Usage: sup [-RsF] [-D num] [file/url]"
+	Usage: ufw [-RsF] [-D num] [file/url]"
 	Flags:
 	    -R                   # Remove the file after uploading.
 	    -s                   # Make a screenshot and upload it instead of a file.
 	    -F                   # Make a fullscreen shot instead of prompting for a window/area. Implies -s.
 	    -D <num>             # Delay the shot by <num> seconds.
 	    -p                   # Make the file private. Requires $secret to be set in the config.
+	    -m                   # Maximum filesize (takes K, M and G suffixes).

 	    secret               # Your personal token. Get it at https://zfh.so/settings_form
