Explain me where/what to find etc.?

Hello there! Im searching here for an hour but i stiil cant find something like working bot programm which allows me to click on .exe and run it :) Im not that pro in this but when i downloaded .au3 file, i rly dont know what to do with it :D
Can any body explain me how to finding here, where to start, how to learn writing my own bot etc...? many thanks!

Download and install AutoIt. This is a scripting program that uses au3 files to execute code.

Yeah you need AutoIt to run au3 files but most of the paid bots are alredy packaged into .exe and they are more stable so i would go for thos ;)
