Format of solution to AMM problem

This is a rather 'soft' question, but I have solved an AMM problem and want to submit a solution. However I couldn't find on the website what format they want it in? They have advice for papers/notes for the AMM, but they don't have any templates for the solution file. Is there any guidance out there/does anyone know where to find such a solution template?

(At least as of a few years ago) they still accepted hand-written solutions from third-world countries. Nowadays, 99 percent of solutions are in LaTeX. Iosif is right: submit PDF format, whether or not the original is in LaTeX. Solutions are submitted at: https://americanmathematicalmonthly.submittable.com/submit
