Tips/advice for making a boxe?

Hey everyone, I just finished making my first box and I hope to submit it soon. I wanted to know if someone has any general advice or tips on finishing touches before I actually submit it for review. For example, what stuff should I clean, things I should get rid of, things I should add, things I need to make sure I have, or any advice that relates to creating boxes for HTB in general.

Thanks for these tips! As someone new to Hack The Box, this guide gives me a clearer idea of what to focus on when approaching a box.
