 ### generating values
 The script gen_values can be used to generate test values
 
 ```
-python gen_values.py [--noise-bits <number of noise bits>] [--number <number of values to generate>]
+usage: gen_values.py [-h] [--noise-bits NOISE_BITS] [--p-bits P_BITS] [--number NUMBER]
+
+Generate test input for AGCD computation
+
+options:
+  -h, --help            show this help message and exit
+  --noise-bits NOISE_BITS
+                        Number of noise bits (default: 5)
+  --p-bits P_BITS       Number of key bits (default: 16)
+  --number NUMBER       Number of numbers to generate (default: 20)
 ```
 
 the output can be directly written to a file
 ```
 python gen_values.py [options] > input.txt
 ```
