-### 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.

-### 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).
