Rules and pushing forward, but how?

So I’ve been using Cursor for several different avenues android Programming, Unreal Engine, C++, C#, MySQL, Python etc and I have done fairly well.

There comes a point when using Cursor that you want to start diving a little deeper, but you don’t want to come here and ask questions out of fear sounding like a not so good user (Yip that’s me).

So I’ve been reading about these rules, I’ve tried to read a few different sites and the main YouTube link on the forum and I am still at a lost.

I am starting to think that moving forward to bigger projects it would be silly not to have rules in place for the AI to follow, otherwise you could be digging a hole and run into issues.

So my question, Is there somewhere I can go or if someone can explain in really simple terms on how to actually start with a rule and really explain to someone who is a complete noob, so when I get proficient at this and others ask, I can point them back here because the forum of great wizkids pushed me in the right direction.

Looking forward to your replies.

Thank you.
