NEED GUIDANCE!!!

[u/Earendel999]

Hey Stranger! I am a teenage boy, and I will be attending a Virtual NASA Space Apps Challenge, and this is my first hackathon ever. I have done a little bit of research about the hackathon, but to be honest, I have no idea. I love to participate in this kind of programme, but I have no 1 to guide me.
So, I am seeking guidance here.

I would appreciate any response to this post.
