+The library is distributed as a Swift framework and can be integrated into your project in following ways:
 
-### Carthage
+#### Carthage
 
-The easiest way is to use the package manager [Carthage](https://github.com/Carthage/Carthage).
+If you use [Carthage](https://github.com/Carthage/Carthage) for managing your dependencies, put OrderedDictionary into your `Cartfile`:
 
-1. Add `github "lukaskubanek/OrderedDictionary"` to your `Cartfile`.
-2. Run `carthage bootstrap`.
-3. Drag either the `OrderedDictionary.xcodeproj` or the `OrderedDictionary.framework` into your project/workspace and link your target against the `OrderedDictionary.framework`.
-4. Make sure the framework [gets copied](https://github.com/Carthage/Carthage#adding-frameworks-to-an-application) to your application bundle.
-5. Import the framework using `import OrderedDictionary`.
+```plain
+github "lukaskubanek/OrderedDictionary"
+```
 
-### Submodule & Xcode Project
+Then, drag either the `OrderedDictionary.xcodeproj` or the `OrderedDictionary.framework` into your project/workspace and link your target against the `OrderedDictionary.framework`. Also make sure that the framework [gets copied](https://github.com/Carthage/Carthage#adding-frameworks-to-an-application) to your application bundle.
 
-Another option is to use [Git submodules](http://git-scm.com/book/en/v2/Git-Tools-Submodules) and integrating the Xcode project `OrderedDictionary.xcodeproj` directly to your Xcode workspace.
+#### Swift Package Manager
+
+Another option is to use the [Swift Package Manager](https://swift.org/package-manager/). If you prefer this option, put OrderedDictionary as a dependency to your `Package.swift`:
+
+```plain
+.package(url: "https://github.com/lukaskubanek/OrderedDictionary.git", from: "2.0.0")
+```
+
+#### Git Submodules
+
+Yet another option is using [Git submodules](http://git-scm.com/book/en/v2/Git-Tools-Submodules) and integrating the Xcode project `OrderedDictionary.xcodeproj` from the submodule directly to your Xcode workspace.
+
+#### ⚠️ Note About CocoaPods
+
+Although there is high demand for [CocoaPods](https://cocoapods.org) support, this method won't be officially supported by this library. Since I'm not using CocoaPods myself and since I think this method will be once replaced by the Swift Package Manager, I don't want to put any effort in maintaining official podspec. If you really want to include this library via CocoaPods, there is still a way by creating a custom podspec. See the last section of [this post](https://guides.cocoapods.org/syntax/podfile.html#pod).
