+byteorder
+=========
+This crate provides convenience methods for encoding and decoding
+numbers in either big-endian or little-endian order.
+
+[![Build status](https://github.com/BurntSushi/byteorder/workflows/ci/badge.svg)](https://github.com/BurntSushi/byteorder/actions)
+[![](https://meritbadge.herokuapp.com/byteorder)](https://crates.io/crates/byteorder)
+
+Dual-licensed under MIT or the [UNLICENSE](https://unlicense.org/).
+
+
+### Documentation
+
+https://docs.rs/byteorder
+
+
+### Installation
+
+This crate works with Cargo and is on
+[crates.io](https://crates.io/crates/byteorder). Add it to your `Cargo.toml`
+like so:
+
+```toml
+[dependencies]
+byteorder = "1"
+```
+
+If you want to augment existing `Read` and `Write` traits, then import the
+extension methods like so:
+
+```rust
+use byteorder::{ReadBytesExt, WriteBytesExt, BigEndian, LittleEndian};
+```
+
+For example:
+
+```rust
+use std::io::Cursor;
+use byteorder::{BigEndian, ReadBytesExt};
+
+let mut rdr = Cursor::new(vec![2, 5, 3, 0]);
+// Note that we use type parameters to indicate which kind of byte order
+// we want!
+assert_eq!(517, rdr.read_u16::<BigEndian>().unwrap());
+assert_eq!(768, rdr.read_u16::<BigEndian>().unwrap());
+```
+
+### `no_std` crates
+
+This crate has a feature, `std`, that is enabled by default. To use this crate
+in a `no_std` context, add the following to your `Cargo.toml`:
+
+```toml
+[dependencies]
+byteorder = { version = "1", default-features = false }
+```
+
+
+### Alternatives
+
+Note that as of Rust 1.32, the standard numeric types provide built-in methods
+like `to_le_bytes` and `from_le_bytes`, which support some of the same use
+cases.
