Hello, I want to ask a question about writing a tutorial. I tried to post a blog in Codeforces many times, but I can't use the LaTeX formula rendered by MathJax normally, and the system will automatically replace it with a picture.

I found that the formulas in many of the contest's tutorials are rendered using MathJax (e.g. Codeforces Round #532 (Div. 2) — Editorial), so I wanted to know how I could do this. In addition, I saw the input box for the tutorial in the problem statement in polygon, but I don't know how to display this tutorial.

I hope I can get your guidance, thank you.

I think it's working only when you enable it from polygon, so only problem statements and editorials have this option, that's what I get from this blog, It'd be nice if it's enabled in normal blogs/comments.

Thank you. I have enabled this in the polygon, my problem statement can be displayed normally using LaTeX, but I don't know how to reference the tutorial in Codeforces.
