 ## Bash-specific instructions
 
 The goal of this exercise is to consider the number of arguments passed to your program.
-If there is exactly one argument, print a greeting message.
-Otherwise print an error message and exit with a non-zero status.
+
+Note that you can pass empty strings as arguments.
+
+`./program ""`
+
+This is different from passing no arguments at all.
+
+`./program`
+
+If your program is run with exactly one argument (even if it is an empty string), treat is as a person's name and print a greeting message.
+If it is run with zero arguments or more than one argument, print an error message and exit with a non-zero status.
