 ## Usage
 
 ```console
-python main.py
-usage: GPTtrace [-h] [-e | -r TEXT] [-u UUID] [-t ACCESS_TOKEN]

+usage: GPTtrace [-h] [-e | -v | -r TEXT] [-u UUID] [-t ACCESS_TOKEN]
 
 Use ChatGPT to write eBPF programs (bpftrace, etc.)
 
 optional arguments:
   -h, --help            show this help message and exit
   -e, --explain         Let ChatGPT explain what's eBPF
+  -v, --verbose         Print the receive
   -r TEXT, --run TEXT   Generate commands using your input with ChatGPT, and run it
   -u UUID, --uuid UUID  Conversion UUID to use, or passed through environment variable `GPTTRACE_CONV_UUID`
   -t ACCESS_TOKEN, --access-token ACCESS_TOKEN
