Git-Flavored Markdown (GFM)
An extended, widely used version is the one used by github; it provides two things in particular to more easily render code blocks.- the triple grave accent to set off code blocks
- interpreting underscores literally so that variable names will read properly; it substitutes "*" to emphasize strings.
