+
+Procedural macros to derive numeric traits in Rust.
+
+## Usage
+
+Add this to your `Cargo.toml`:
+
+```toml
+[dependencies]
+num-traits = "0.2"
+num-derive = "0.3"
+```
+
+and this to your crate root:
+
+```rust
+#[macro_use]
+extern crate num_derive;
+```
+
+Then you can derive traits on your own types:
+
+```rust
+#[derive(FromPrimitive, ToPrimitive)]
+enum Color {
+    Red,
+    Blue,
+    Green,
+}
+```
+
+## Optional features
+
+- **`full-syntax`** — Enables `num-derive` to handle enum discriminants
+  represented by complex expressions. Usually can be avoided by
+  [utilizing constants], so only use this feature if namespace pollution is
+  undesired and [compile time doubling] is acceptable.
+
+[utilizing constants]: https://github.com/rust-num/num-derive/pull/3#issuecomment-359044704
+[compile time doubling]: https://github.com/rust-num/num-derive/pull/3#issuecomment-359172588
+
+## Releases
+
+Release notes are available in [RELEASES.md](RELEASES.md).
+
+## Compatibility
