Lite Markdown cheat sheet

In order to help users can using Markdown, I use cheat sheet to help them. In addition, it should be small and includes some important references, so I remove some redundant cases.

You can click here to download. By the way, I have this demo using this file.

I included CSS in this file too (because I'm lazy), hope you ignore this problem :)

p/s: I wrote a new tip about truncate a string written by Markdown format.
References: I complied from a cheat sheet.
