= Publish your material even if it is not perfect
Just make it very clear what you've tried, what you observed, and what you don't understand if anything at all.
This will already open up room for others to come and expand on your attempt, and you are more likely to learn the answers to your questions as they do.
And there's a good chance someone who knows more than you will come along and correct or teach you something new about the subject. For example, this has happened countless times to <Ciro Santilli> when doing <Ciro Santilli's Stack Overflow contributions>.
Perfect is the enemy of good.
