Markdown is a simple markdown language for producing HTML web pages. Below I’ll show markdown code, and then how that code looks when rendered to HTML:

Headings

Prose

It was the best of times, it was the worst of times, it was the age of wisdom, 
it was the age of foolishness, it was the epoch of belief, it was the epoch of 
incredulity, it was the season of Light, it was the season of Darkness, it was 
the spring of hope, it was the winter of despair, we had everything before us, 
we had nothing before us, we were all going direct to Heaven, we were all going 
direct the other way – in short, the period was so far like the present period, 
that some of its noisiest authorities insisted on its being received, for good 
or for evil, in the superlative degree of comparison only.
