 # AttributedText
 
-A description of this package.
+AttributedText is a Swift µpackage that provides `NSAttributedString` rendering in SwiftUI by wrapping either an `NSTextView` or a `UITextView` depending on the platform.
+
+## Supported Platforms
+
+* macOS 11.0+
+* iOS 14.0+
+* tvOS 14.0+
+
+## Usage
+```swift
+import AttributedText
+
+struct ContentView: View {
+    private let attributedString: NSAttributedString = {
+        let result = NSMutableAttributedString(
+            string: """
+            After the Big Bang
+            A brief summary of time
+            Life on earth
+            10 billion years
+            You reading this
+            13.7 billion years
+            """
+        )
+
+        result.addAttributes([.font: UIFont.preferredFont(forTextStyle: .title1)], range: NSRange(location: 0, length: 18))
+        result.addAttributes([.link: URL(string: "https://en.wikipedia.org/wiki/Big_Bang")!], range: NSRange(location: 10, length: 8))
+        result.addAttributes([.font: UIFont.preferredFont(forTextStyle: .body)], range: NSRange(location: 19, length: 23))
+        result.addAttributes([.font: UIFont.preferredFont(forTextStyle: .title2)], range: NSRange(location: 43, length: 13))
+        result.addAttributes([.font: UIFont.preferredFont(forTextStyle: .body)], range: NSRange(location: 57, length: 16))
+        result.addAttributes([.font: UIFont.preferredFont(forTextStyle: .title2)], range: NSRange(location: 74, length: 16))
+        result.addAttributes([.font: UIFont.preferredFont(forTextStyle: .body)], range: NSRange(location: 91, length: 18))
+
+        return result
+    }()
+
+    var body: some View {
+        AttributedText(attributedString)
+            .background(Color.gray.opacity(0.5))
+            .accentColor(.purple)
+    }
+}
+```
+
+![iOSScreenshot](iOS_screenshot.png)
+
+An `AttributedText` view takes all the available width and adjusts its height to fit the contents.
+
+To change the text alignment or line break mode, you need to add a `.paragraphStyle` attribute to the attributed string.
+
+## Installation
+You can add AttributedText to an Xcode project by adding it as a package dependency.
+1. From the **File** menu, select **Swift Packages › Add Package Dependency…**
+1. Enter `https://github.com/gonzalezreal/AttributedText` into the package repository URL text field
+1. Link **AttributedText** to your application target
