+
+Blazing fast Markdown rendering in Swift, built upon [cmark](https://github.com/jgm/cmark).
+
+Is your app using it? [Let me know!](mailto:rob@desideratalabs.co)
+
+### Installation
+
+Quickly install using [CocoaPods](https://cocoapods.org): 
+
+```ruby
+pod 'Down'
+```
+
+### Robust Performance
+
+>[cmark](https://github.com/jgm/cmark) can render a Markdown version of War and Peace in the blink of an eye (127 milliseconds on a ten year old laptop, vs. 100-400 milliseconds for an eye blink). In our [benchmarks](https://github.com/jgm/cmark/blob/master/benchmarks.md), cmark is 10,000 times faster than the original Markdown.pl, and on par with the very fastest available Markdown processors.
+
+> The library has been extensively fuzz-tested using [american fuzzy lop](http://lcamtuf.coredump.cx/afl). The test suite includes pathological cases that bring many other Markdown parsers to a crawl (for example, thousands-deep nested bracketed text or block quotes).
+
+### Output Formats
+* HTML
+* XML
+
+### API
+
+
+### Supports
+Swift, ARC & iOS 8+
+
+### Markdown Specification
+
+Down is built upon the [CommonMark](http://commonmark.org) specification.
+
+### A little help from my friends
+Please feel free to fork and create a pull request for bug fixes or improvements, being sure to maintain the general coding style, adding tests, and adding comments as necessary.
+
+### Credit
+This library is a wrapper around [cmark](https://github.com/jgm/cmark), which is built upon the [CommonMark](http://commonmark.org) Markdown specification.
