 # How to run
-__Example config:__ 
+## Example config:
+
 **Linux / Windows:**
 ```shell 
 python main.py --fingerprint '198e9fe586114844f6a4eaca5069b41a7ed43fb5a2df84892b69826d64573e39' --path-license examples/license.lic --path-machine examples/machine.lic
 ```
 
-__Normal config:__  
+## 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`.  
+* Replace the public key from [keygen.sh](keygen.sh) line 63 of `main.py`.
+* Get your machine file on [keygen.sh](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:
 
 **Linux / Windows:**
 ```shell
 python main.py
 ```
-(You need to run it as root in Linux because it needs to access `/dev/sda` to get the serial number of your machine.)
