Add a screen to help new users understand keyboard / game controller use

New user to PC games... (to give you a hit of my age, started with the ATARI). Where can I find the INSTRUCTIONS on how to move about and take actions in the game? Neither the 'old classic' F1 key, nor the 'setting / controls' (in the game), nor your website (https://www.rocketwerkz.com) seem to not give information nor guidance,
Thanks,
Henry
