-Example config : `python3 main.py --fingerprint '198e9fe586114844f6a4eaca5069b41a7ed43fb5a2df84892b69826d64573e39' --path-license examples/license.lic --path-machine examples/machine.lic`
+# How to run
+__Example config:__ 
+```shell 
+python main.py --fingerprint '198e9fe586114844f6a4eaca5069b41a7ed43fb5a2df84892b69826d64573e39' --path-license examples/license.lic --path-machine examples/machine.lic
+```
+
+__Normal config:__  
+* Your fingerprint should be the hash of the serial number of your machine (you can execute the program to see it) computed with **SHA3_512** ([Online Converter](https://emn178.github.io/online-tools/sha3_512.html)).  
+* Get your machine file on keygen.sh and put the raw license key in a new file named `license.lic`.  
+* Put your `machine.lic` & `license.lic` in the same folder as `main.py` and run:
+```shell
+python main.py
+```
