+# enum-map
+
+A library providing enum map providing type safe enum array. It is
+implemented using regular Rust arrays, so using them is as fast
+as using regular Rust arrays.
+
+This crate follows the "N minus two" MSRV policy. This means that it
+supports the current Rust release, as well as the two before that.
+
+## Examples
+
+```rust
+#[macro_use]
+extern crate enum_map;
+
+use enum_map::EnumMap;
+
+#[derive(Debug, Enum)]
+enum Example {
+    A,
+    B,
+    C,
+}
+
+fn main() {
+    let mut map = enum_map! {
+        Example::A => 1,
+        Example::B => 2,
+        Example::C => 3,
+    };
+    map[Example::C] = 4;
+
+    assert_eq!(map[Example::A], 1);
+
+    for (key, &value) in &map {
+        println!("{:?} has {} as value.", key, value);
+    }
+}
+```
