What is markdown

Markdown is a lightweight markup language that allows people to write documents in plain text format that is easy to read and write.

Markdown thinks that compared with word, its biggest advantage is that it can complete typesetting while writing words, so that it can completely devote its writing energy to the content.

Moreover, markdown can export files of various formats, which is much easier to use than the wonderful version of word.
