Re: Is it okay if I use Windows PowerShell for changing/adding recipes?

Those numbers on the side are just line numbers, they help you read code and find errors faster, you dont really “use” them for anything. The text in the console is mainly logs and errors, so if something breaks thats where you look, otherwise you can mostly ignore it. You dont need Visual Studio btw, you can use simpler editors like Visual Studio Code or even Notepad++ and be totally fine.
