+
+`Integer` trait and functions for Rust.
+
+## Usage
+
+Add this to your `Cargo.toml`:
+
+```toml
+[dependencies]
+num-integer = "0.1"
+```
+
+and this to your crate root:
+
+```rust
+extern crate num_integer;
+```
+
+## 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-integer]
+version = "0.1.36"
+default-features = false
+```
+
+There is no functional difference with and without `std` at this time, but
+there may be in the future.
+
+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-integer` crate is tested for rustc 1.8 and greater.
