Installation is pretty standard. It follows the usual procedure of generating an .exe file with an Ahk2exe utility:

• Install AutoHotkey Version 2 (Attention! Version 2, my script is written with ahk2 syntax).
• Run it
• Choose Compile option that will download/open Ahk2exe application.
• Choose main.ahk from current repo as Source (script file).
• Press "Convert"
• It will generate main.exe file which you can just run for keybinds to work
• Now if you want the .exe to work persistent through Windows reboots follow the section below

• Make a shortcut for main.exe generated in the previous section;
• Put the shortcut into special Windows Startup folder (press Win+R and type shell:startup to reach there);
• Done! Now the script should be running on every PC restart.
