Markdown is a lightweight markup language. In this article I'll introduce you to Markdown, give a few examples and an overview of markdown-related software.
A lightweight markup language is a markup language with a easy and simple syntax, designed to be easy for a human to enter with a simple text editor, and easy to read in its raw form. Lightweight markup languages are used in applications where people might be expected to read the document source as well as the rendered output. For instance, a person downloading a software library might prefer to read the documentation in a text editor rather than a browser. Another application is for entry in web-based publishing, such as weblogs and wikis, where the input interface is a simple text box. The server software converts the input to a common document markup language like HTML or XHTML.
From the creator of markdown:
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). [DaringFireball.net]
MarkDown lets you write for the web, using simple syntax which is understandable even if it is not converted to HTML.
There are a lot of sites that support and use markdown. I will also mention a few editors with markdown support.
Altough every text editor is a markdown editor, these applications have extra features like live preview or a handy button bar.
This is a list sorted by Operating System
Below I'll give some examples, both HTML and Markdown code.
# This is an H1 ## This is an H2 ###### This is an H6
<h1>This is an H1</h1> <h2>This is an H2</h2> <h6>This is an H6</h2>
