 ## Usage
 
 Winit is a window creation and management library. It can create windows and lets you handle
 events (for example: the window being resized, a key being pressed, a mouse movement, etc.)
-produced by window.
+produced by the window.
 
 Winit is designed to be a low-level brick in a hierarchy of libraries. Consequently, in order to
 show something on the window you need to use the platform-specific getters provided by winit, or
 another library.
 
-```rust
-use winit::{
-    event::{Event, WindowEvent},
-    event_loop::{ControlFlow, EventLoop},
-    window::WindowBuilder,
-};
-
-fn main() {
-    let event_loop = EventLoop::new();
-    let window = WindowBuilder::new().build(&event_loop).unwrap();
-
-    event_loop.run(move |event, _, control_flow| {
-        *control_flow = ControlFlow::Wait;
-
-        match event {
-            Event::WindowEvent {
-                event: WindowEvent::CloseRequested,
-                window_id,
-            } if window_id == window.id() => *control_flow = ControlFlow::Exit,
-            _ => (),

+## MSRV Policy
+
+This crate's Minimum Supported Rust Version (MSRV) is **1.70**. Changes to
+the MSRV will be accompanied by a minor version bump.
+
+As a **tentative** policy, the upper bound of the MSRV is given by the following
+formula:
+
+```
+min(sid, stable - 3)
+```
+
+Where `sid` is the current version of `rustc` provided by [Debian Sid], and
+`stable` is the latest stable version of Rust. This bound may be broken in case of a major ecosystem shift or a security vulnerability.
+
+[Debian Sid]: https://packages.debian.org/sid/rustc
+
+The exception is for the Android platform, where a higher Rust version
+must be used for certain Android features. In this case, the MSRV will be
+capped at the latest stable version of Rust minus three. This inconsistency is
+not reflected in Cargo metadata, as it is not powerful enough to expose this
+restriction.
+
+All crates in the [`rust-windowing`] organizations have the
+same MSRV policy.
