+
+[Rust](https://www.rust-lang.org) implementations of [string similarity metrics]:
+  - [Hamming]
+  - [Levenshtein] - distance & normalized
+  - [Optimal string alignment]
+  - [Damerau-Levenshtein] - distance & normalized
+  - [Jaro and Jaro-Winkler] - this implementation of Jaro-Winkler does not limit the common prefix length
+  - [Sørensen-Dice]
+
+The normalized versions return values between `0.0` and `1.0`, where `1.0` means
+an exact match.
+
+There are also generic versions of the functions for non-string inputs.
+
+## Installation
+
+`strsim` is available on [crates.io](https://crates.io/crates/strsim). Add it to
+your `Cargo.toml`:
+```toml
+[dependencies]
+strsim = "0.10.0"
+```
+
+## Usage
+
+Go to [Docs.rs](https://docs.rs/strsim/) for the full documentation. You can
+also clone the repo, and run `$ cargo doc --open`.
+
+### Examples
+
+```rust
+extern crate strsim;
+
+use strsim::{hamming, levenshtein, normalized_levenshtein, osa_distance,
+             damerau_levenshtein, normalized_damerau_levenshtein, jaro,
+             jaro_winkler, sorensen_dice};
+
+fn main() {
+    match hamming("hamming", "hammers") {
+        Ok(distance) => assert_eq!(3, distance),
+        Err(why) => panic!("{:?}", why)
+    }
+
+    assert_eq!(levenshtein("kitten", "sitting"), 3);
+
+    assert!((normalized_levenshtein("kitten", "sitting") - 0.571).abs() < 0.001);
+
+    assert_eq!(osa_distance("ac", "cba"), 3);
+
+    assert_eq!(damerau_levenshtein("ac", "cba"), 2);
+
+    assert!((normalized_damerau_levenshtein("levenshtein", "löwenbräu") - 0.272).abs() <
+            0.001);
+
+    assert!((jaro("Friedrich Nietzsche", "Jean-Paul Sartre") - 0.392).abs() <
+            0.001);
+
+    assert!((jaro_winkler("cheeseburger", "cheese fries") - 0.911).abs() <
+            0.001);
+
+    assert_eq!(sorensen_dice("web applications", "applications of the web"),
+        0.7878787878787878);
+}
+```
+
+Using the generic versions of the functions:
+
+```rust
+extern crate strsim;
+
+use strsim::generic_levenshtein;
+
+fn main() {
+    assert_eq!(2, generic_levenshtein(&[1, 2, 3], &[0, 2, 5]));
+}
+```
+
+## Contributing
+
+If you don't want to install Rust itself, you can run `$ ./dev` for a
+development CLI if you have [Docker] installed.
+
+Benchmarks require a Nightly toolchain. Run `$ cargo +nightly bench`.
