 ## Tests
 
-HTMLKit passes all of the [HTML5Lib](https://github.com/html5lib/html5lib-tests) Tokenizer and Tree Construction tests except for the Blink changes introduced on the 16.09.2015. The `html5lib-tests` is configured as a git-submodule. If you plan to run the tests, do not forget to pull it too.

+# Installation
+
+## Carthage
+
+[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.
+
+If you don't have Carthage yet, you can install it with Homebrew using the following command:
+
+```bash
+$ brew update
+$ brew install carthage
+```
+
+To add `HTMLKit` as a dependency into your project using Carthage just add the following line in your `Cartfile`:
+
+```
+github "iabudiab/HTMLKit"
+```
+
+Then run the following command to build the framework and drag the built `HTMLKit.framework` into your Xcode project.
+
+```bash
+$ carthage update
+```
+
+## CocoaPods
+
+[CocoaPods](http://cocoapods.org) is a dependency manager for Cocoa projects.
+
+If you don't have CocoaPods yet, you can install it with the following command:
+
+```bash
+$ gem install cocoapods
+```
+
+To add `HTMLKit` as a dependency into your project using CocoaPods just add the following in your `Podfile`:
+
+```ruby
+use_frameworks!
+
+target 'MyTarget' do
+  pod 'HTMLKit', '~> 2.0'
+end
+```
+
+Then, run the following command:
+
+```bash
+$ pod install
+```
+
+## Swift Package Manager
+
+[Swift Package Manager](https://github.com/apple/swift-package-manager) is the package manager for the Swift programming language.
+
+Add `HTMLKit` to your `Package.swift` dependecies:
+
+```swift
+.Package(url: "https://github.com/iabudiab/HTMLKit", majorVersion: 2)
+```
+
+Then run:
+
+```bash
+$ swift build
+```
+
+## Manually
+
+1- Add `HTMLKit` as git submodule
+
+```bash
+$ git submodule add https://github.com/iabudiab/HTMLKit.git
+```
+
+2- Open the `HTMLKit` folder and drag'n'drop the `HTMLKit.xcodeproj` into the Project Navigator in Xcode to add it as a sub-project.
+
+3- In the General panel of your target add `HTMLKit.framework` under the `Embedded Binaries`
