+
+An opinionated GUI runtime for Rust, heavily inspired by Elm.
+
+## Features
+  * Simple, easy to use API
+  * Responsive, flexbox-based layouting
+  * Type-safe, reactive programming model without weak references
+  * Built-in widgets
+  * Custom widget support
+  * Renderer-agnostic runtime
+
+## Usage
+Add `iced` as a dependency in your `Cargo.toml`:
+
+```toml
+iced = "0.1"
+```
+
+__Iced moves fast and the `master` branch can contain breaking changes!__ If
+you want to learn about a specific release, check out [the release list].

+
+## Overview
+Here is an example showcasing an interactive counter that can be incremented and
+decremented using two different buttons:
+
+```rust
+use iced::{button, Button, Column, Text};
+use crate::MyRenderer;
+
+struct Counter {
+    // The counter value
+    value: i32,
+
+    // Local state of the two counter buttons
+    // This is internal widget state that may change outside our update
+    // logic
+    increment_button: button::State,
+    decrement_button: button::State,
+}
+
+// The user interactions we are interested on
+#[derive(Debug, Clone, Copy)]
+pub enum Message {
+    IncrementPressed,
+    DecrementPressed,
+}
+
+impl Counter {
+    // The update logic, called when a message is produced
+    fn react(&mut self, message: Message) {
+        // We update the counter value after an interaction here
+        match message {
+            Message::IncrementPressed => {
+                self.value += 1;
+            }
+            Message::DecrementPressed => {
+                self.value -= 1;
+            }
+        }
+    }
+
+    // The layout logic, describing the different components of the counter
+    fn layout(&mut self, window: &Window) -> Element<Message, MyRenderer> {
+        // We use a column so the elements inside are laid out vertically
+        Column::new()
+            .push(
+                // The increment button. We tell it to produce an
+                // `IncrementPressed` message when pressed
+                Button::new(&mut self.increment_button, "+")
+                    .on_press(Message::IncrementPressed),
+            )
+            .push(
+                // We show the value of the counter here
+                Text::new(&self.value.to_string()).size(50),
+            )
+            .push(
+                // The decrement button. We tell it to produce a
+                // `DecrementPressed` message when pressed
+                Button::new(&mut self.decrement_button, "-")
+                    .on_press(Message::DecrementPressed),
+            )
+            .into() // We can return a generic `Element` and avoid breaking
+                    // changes if we redesign the counter in the future.
+    }
+}
+```
