Depends on: MultiMarkdown
This is a folk of swaroopch's vim-markdown-preview. It is working well on Windows now.
In Vim, (optionally) select some text and then press :MarkdownPreview and see the rendered results in a browser.
Useful when writing long-form text in Markdown but ultimately want to (1) send the rendered content in a rich email or (2) post to a blog in HTML format, etc.
