You can hardly call the author out of line for retaliating when your initial comment was not constructive or necessary:
It is the same as using any other FiveM resource. If you want help, ask for it politely. Don’t come at him like that and expect him to play nice. Configuring it is pretty self explanatory. Replace the logo.png and bg0-7.png with the images you want displayed. Look in the config.js to find where to add your youtube ID’s etc.
Next time you want help or clarification with something, ask reasonably. You won’t make any friends here with that sort of attitude
