 #### sudo elevation
 
-The elevate module can work with sudo for unix operating systems.
-You must configure sudo to not ask a password for the specific command you're trying to run.
+Initially designed for Windows UAC, command_runner.elevate can also elevate privileges on Linux, using the sudo command.
+This is mainly designed for PyInstaller / Nuitka executables, as it's really not safe to allow automatic privilege elevation of a Python interpreter.
+
+Example for a binary in `/usr/local/bin/my_compiled_python_binary`
+
+You'll have to allow this file to be run with sudo without a password prompt.
+This can be achieved in `/etc/sudoers` file.
 
+Example for Redhat / Rocky Linux, where adding the following line will allow the elevation process to succeed without password:
+```
+someuser ALL= NOPASSWD:/usr/local/bin/my_compiled_python_binary
+```
