+
+Numeric traits for generic mathematics in Rust.
+
+## Usage
+
+Add this to your `Cargo.toml`:
+
+```toml
+[dependencies]
+num-traits = "0.2"
+```
+
+and this to your crate root:
+
+```rust
+extern crate num_traits;
+```
+
+## Features
+
+This crate can be used without the standard library (`#![no_std]`) by disabling
+the default `std` feature. Use this in `Cargo.toml`:
+
+```toml
+[dependencies.num-traits]
+version = "0.2"
+default-features = false
+# features = ["libm"]    # <--- Uncomment if you wish to use `Float` and `Real` without `std`
+```
+
+The `Float` and `Real` traits are only available when either `std` or `libm` is enabled.  
+The `libm` feature is only available with Rust 1.31 and later ([see PR #99](https://github.com/rust-num/num-traits/pull/99)).
+
+The `FloatCore` trait is always available.  `MulAdd` and `MulAddAssign` for `f32`
+and `f64` also require `std` or `libm`, as do implementations of signed and floating-
+point exponents in `Pow`.
+
+Implementations for `i128` and `u128` are only available with Rust 1.26 and
+later.  The build script automatically detects this, but you can make it
+mandatory by enabling the `i128` crate feature.
+
+## Releases
+
+Release notes are available in [RELEASES.md](RELEASES.md).
+
+## Compatibility
+
+The `num-traits` crate is tested for rustc 1.8 and greater.
