+
+Encoding and decoding data into/from hexadecimal representation.
+
+## Examples
+
+Encoding a `String`
+
+```rust
+let hex_string = hex::encode("Hello world!");
+
+println!("{}", hex_string); // Prints "48656c6c6f20776f726c6421"
+```
+
+Decoding a `String`
+
+```rust
+let decoded_string = hex::decode("48656c6c6f20776f726c6421");
+
+println!("{}", decoded_string); // Prints "Hello world!"
+```
+
+You can find the [documentation](https://docs.rs/hex) here.
+
+## Installation
+
+In order to use this crate, you have to add it under `[dependencies]` to your `Cargo.toml`
+
+```toml
+[dependencies]
+hex = "0.4"
+```
+
+By default this will import `std`, if you are working in a
+[`no_std`](https://rust-embedded.github.io/book/intro/no-std.html)
+environment you can turn this off by adding the following
+
+```toml
+[dependencies]
+hex = { version = "0.4", default-features = false }
+```
+
+## Features
+
+- `std`:
+  Enabled by default. Add support for Rust's libstd types.
+- `serde`:
+  Disabled by default. Add support for `serde` de/serializing library.
+  See the `serde` module documentation for usage.
