+
+### Installation
+
+Note: Swift 4 support is now on the `master` branch and any tag >= 0.4.x (Swift 3 is 0.3.x)
+
+Quickly install using [CocoaPods](https://cocoapods.org):
+
+```ruby
+pod 'Down'
+```
+
+Or [Carthage](https://github.com/Carthage/Carthage):
+
+```
+github "iwasrobbed/Down"
+```
+Due to limitations in Carthage regarding platform specification, you need to define the platform with Carthage.
+
+e.g.
+
+```carthage update --platform iOS```
+
+Or manually install:
+
+1. Clone this repository
+2. Build the Down project
+3. Add the resulting framework file to your project
+4. ?
+5. Profit
+
+### Robust Performance
+
+>[cmark](https://github.com/commonmark/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/commonmark/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
+* Web View (see DownView class)
+* HTML
+* XML
+* LaTeX
+* groff man
+* CommonMark Markdown
+* NSAttributedString
+* AST (abstract syntax tree)
+
+### View Rendering
+
+The `DownView` class offers a very simple way to parse a UTF-8 encoded string with Markdown and convert it to a web view that can be added to any view:
+
+```swift
+let downView = try? DownView(frame: self.view.bounds, markdownString: "**Oh Hai**") {
+// Optional callback for loading finished
+}
+// Now add to view or constrain w/ Autolayout
+// Or you could optionally update the contents at some point:
+try? downView?.update(markdownString:  "## [Google](https://google.com)") {
+// Optional callback for loading finished
+}
+```
+
+Meta example of rendering this README:
+
+![Example gif](Images/ohhai.gif)
+
+### Parsing API
+
+The `Down` struct has everything you need if you just want out-of-the-box setup for parsing and conversion.
+
+```swift
+let down = Down(markdownString: "## [Down](https://github.com/iwasrobbed/Down)")
+
+// Convert to HTML
+let html = try? down.toHTML()
+// "<h2><a href=\"https://github.com/iwasrobbed/Down\">Down</a></h2>\n"
+
+// Convert to XML
+let xml = try? down.toXML()
+// "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<!DOCTYPE document SYSTEM \"CommonMark.dtd\">\n<document xmlns=\"http://commonmark.org/xml/1.0\">\n  <heading level=\"2\">\n    <link destination=\"https://github.com/iwasrobbed/Down\" title=\"\">\n      <text>Down</text>\n    </link>\n  </heading>\n</document>\n"
+
+// Convert to groff man
+let man = try? down.toGroff()
+// ".SS\nDown (https://github.com/iwasrobbed/Down)\n"
+
+// Convert to LaTeX
+let latex = try? down.toLaTeX()
+// "\\subsection{\\href{https://github.com/iwasrobbed/Down}{Down}}\n"
+
+// Convert to CommonMark Markdown
+let commonMark = try? down.toCommonMark()
+// "## [Down](https://github.com/iwasrobbed/Down)\n"
+
+// Convert to an attributed string
+let attributedString = try? down.toAttributedString()
+// NSAttributedString representation of the rendered HTML;
+// by default, uses a stylesheet that matches NSAttributedString's default font,
+// but you can override this by passing in your own, using the 'stylesheet:' parameter.
+
+// Convert to abstract syntax tree
+let ast = try? down.toAST()
+// Returns pointer to AST that you can manipulate
+
+```
+
+### Rendering Granularity
+
+If you'd like more granularity for the output types you want to support, you can create your own struct conforming to at least one of the renderable protocols:
+
+* DownHTMLRenderable
+* DownXMLRenderable
+* DownLaTeXRenderable
+* DownGroffRenderable
+* DownCommonMarkRenderable
+* DownASTRenderable
+* DownAttributedStringRenderable
+
+Example:
+
+```swift
+public struct MarkdownToHTML: DownHTMLRenderable {
+/**
+A string containing CommonMark Markdown
+*/
+public var markdownString: String
+
+/**
+Initializes the container with a CommonMark Markdown string which can then be rendered as HTML using `toHTML()`
+
+- parameter markdownString: A string containing CommonMark Markdown
+
+- returns: An instance of Self
+*/
+@warn_unused_result
+public init(markdownString: String) {
+self.markdownString = markdownString
+}
+}
+```
+
+### Configuration of `DownView`
+
+`DownView` can be configured with a custom bundle using your own HTML / CSS or to do things like supporting
+Dynamic Type or custom fonts, etc. It's completely configurable.
+
+This option can be found in [DownView's instantiation function](https://github.com/iwasrobbed/Down/blob/master/Source/Views/DownView.swift#L26).
+
+##### Prevent zoom
+
+The default implementation of the `DownView` allows for zooming in the rendered content. If you want to disable this, then you’ll need to instantiate the `DownView` with a custom bundle where the `viewport` in `index.html` has been assigned `user-scalable=no`. More info can be found [here](https://github.com/iwasrobbed/Down/pull/30).
+
+### Options
+
+Each protocol has options that will influence either rendering or parsing:
+
+```swift
+/**
+Default options
+*/
+public static let `default` = DownOptions(rawValue: 0)
+
+// MARK: - Rendering Options
+
+/**
+Include a `data-sourcepos` attribute on all block elements
+*/
+public static let sourcePos = DownOptions(rawValue: 1 << 1)
+
+/**
+Render `softbreak` elements as hard line breaks.
+*/
+public static let hardBreaks = DownOptions(rawValue: 1 << 2)
+
+/**
+Suppress raw HTML and unsafe links (`javascript:`, `vbscript:`,
+`file:`, and `data:`, except for `image/png`, `image/gif`,
+`image/jpeg`, or `image/webp` mime types).  Raw HTML is replaced
+by a placeholder HTML comment. Unsafe links are replaced by
+empty strings.
+*/
+public static let safe = DownOptions(rawValue: 1 << 3)
+
+// MARK: - Parsing Options
+
+/**
+Normalize tree by consolidating adjacent text nodes.
+*/
+public static let normalize = DownOptions(rawValue: 1 << 4)
+
+/**
+Validate UTF-8 in the input before parsing, replacing illegal
+sequences with the replacement character U+FFFD.
+*/
+public static let validateUTF8 = DownOptions(rawValue: 1 << 5)
+
+/**
+Convert straight quotes to curly, --- to em dashes, -- to en dashes.
+*/
+public static let smart = DownOptions(rawValue: 1 << 6)
+```
+
+### Supports
+Swift; iOS 9+, tvOS 9+, macOS 10.11+
+
+### 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.

 ### 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.

+### Configuration of `DownView`
+
+`DownView` can be configured with a custom bundle using your own HTML / CSS or to do things like supporting
+Dynamic Type or custom fonts, etc. It's completely configurable.
+
+This option can be found in [DownView's instantiation function](https://github.com/johnxnguyen/Down/blob/master/Source/Views/DownView.swift#L26).
+
+##### Prevent zoom
+
+The default implementation of the `DownView` allows for zooming in the rendered content. If you want to disable this, then you’ll need to instantiate the `DownView` with a custom bundle where the `viewport` in `index.html` has been assigned `user-scalable=no`. More info can be found [here](https://github.com/johnxnguyen/Down/pull/30).
