This article recommends a very useful note-taking tool-Markdown! This paper is mainly aimed at: for those friends who have never used markdown or can't use it, they often need to take systematic and long notes, which are mixed with some mathematical formulas. This article doesn't say much about how to use it, but it will give some existing links for your reference.

So first you must ask, what is markdown? Why do I take it as a note artifact? Simply listen to me.

First, we quote an explanation from Wikipedia. If you don't want to read so many words, just remember lightweight, markup language and support charts, tables and mathematical formulas.

Markdown is a lightweight markup language, which allows people to "write documents in plain text format that is easy to read and write, and then convert them into effective XHTML (or HTML) documents".

Markdown is lightweight, easy to read and write, and supports pictures, charts and mathematical expressions. At present, Markdown is widely used by many websites to write help documents or post messages on forums. For example: GitHub, reddit, Diaspora, Stack Exchange, OpenStreetMap, SourceForge, etc. Even Markdown can be used to write e-books. -From Wikipedia /p/32309940
