Hey @felipecrs!

Thanks for your contribution! Could you provide more context about the rules? Because for me it's okay have the sections using h3 or ###.

Hi @fanny!

Try here: https://dlaa.me/markdownlint/ (and paste in the original file)

Or if you have VSCode, try the markdownlint extension.

About the ###: https://github.com/DavidAnson/markdownlint/blob/main/doc/Rules.md#md001---heading-levels-should-only-increment-by-one-level-at-a-time

LGTM and seems to effectively fix rule 1.
