There are 3 ways to do this:
- You can either use a text editor that has a built in Markdown previewer. On Mac there's Mou, and on Windows there's MarkdownPad.
- You can keep using your favorite text editor and use an external Markdown preview program. We like the idea of this, since we are very partial to our text editors. If you use a Mac, you can use Marked, which is a standalone a Markdown preview program.
- You can use a WYSIWIG Markdown editor. See this article for more information.
