+## Windows collection types
+
+The [windows-collections](https://crates.io/crates/windows-collections) crate provides stock collection support for Windows APIs.
+
+* [Getting started](https://kennykerr.ca/rust-getting-started/)
+* [Samples](https://github.com/microsoft/windows-rs/tree/master/crates/samples)
+* [Releases](https://github.com/microsoft/windows-rs/releases)
+
+Start by adding the following to your Cargo.toml file:
+
+```toml
+[dependencies.windows-collections]
+version = "0.3"
+```
+
+Use the Windows collection types as needed:
+
+```rust
+use windows_collections::*;
+
+let numbers = IIterable::<i32>::from(vec![1, 2, 3]);
+
+for value in numbers {
+    println!("{value}");
+}
+```
+
+Naturally, the Windows collection types work with other Windows crates:
+
+```rust
+use windows_collections::*;
+use windows_strings::*;
+
+let greetings =
+    IVectorView::<HSTRING>::from(vec![HSTRING::from("hello"), HSTRING::from("world")]);
+
+for value in greetings {
+    println!("{value}");
+}
+
+let map = std::collections::BTreeMap::from([("one".into(), 1), ("two".into(), 2)]);
+let map = IMapView::<HSTRING, i32>::from(map);
+
+assert_eq!(map.Lookup(h!("one")).unwrap(), 1);
+assert_eq!(map.Lookup(h!("two")).unwrap(), 2);
+```
