簡介
這是官方網站上介紹
Markdown is a text-to-HTML conversion tool for web writers. Markdown allows you to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid XHTML (or HTML).
Thus, “Markdown” is two things: (1) a plain text formatting syntax; and (2) a software tool, written in Perl, that converts the plain text formatting to HTML. See the Syntax page for details pertaining to Markdown’s formatting syntax. You can try it out, right now, using the online Dingus.
The overriding design goal for Markdown’s formatting syntax is to make it as readable as possible. The idea is that a Markdown-formatted document should be publishable as-is, as plain text, without looking like it’s been marked up with tags or formatting instructions. While Markdown’s syntax has been influenced by several existing text-to-HTML filters, the single biggest source of inspiration for Markdown’s syntax is the format of plain text email.
OpenFoundry 上的介紹
Markdown 是一個輕量的標記語言，主要用於讓人們可以不用 HTML 複雜繁長的語法就能夠標記格式而達到管理文件的目的。Markdown 是由 John Gruber 跟 Aaron Swartz 所創造出來的。他們希望能夠讓人們可以用易讀，易寫的簡單文件格式，透過工具格式化轉成 HTML。經過多年的發展，Markdown 已經成為許多人做筆記的第一選擇了。原因除了其簡潔直觀的語法還有就是長期來慢慢累積出來的周邊工具。Markdown 已經不再僅僅只是用於標記基礎格式的語言了。圍繞著 Markdown 產生出來的工具組已經可以讓這個標記語言作到細緻的排版。已經有為數不少的人用 Markdown 來創造他們的數位著作。知名的源碼版本控制服務網站 GitHub 用 Markdown 作為他們預設支援的文本格式。其它還有許多的服務都支援 Markdown 作為他們優先支援的格式。
Markdown其實是 (1) 一種文本語法 （2) 一個轉化文件成HTML格式的軟體工具，他的工具是用Perl寫成。

为什么作家应该用 Markdown 保存自己的文稿Markdown写作浅谈
其它
CommonMark：有人試著標準化 Markdown，這是在他們官網上寫的：「We propose a standard, unambiguous syntax specification for Markdown, along with a suite of comprehensive tests to validate Markdown implementations against this specification. We believe this is necessary, even essential, for the future of Markdown.」。當初他們好像想要用 Standard Markdown 的名字，但讓 Markdown的原創者非常 infuriating，這篇文章是他們的道歉。
