+
+This library is a port of the Diff component of [Diff Match Patch] to Rust. The
+diff implementation is based on [Myers' diff algorithm] but includes some
+[semantic cleanups] to increase human readability by factoring out commonalities
+which are likely to be coincidental.
+
+Diff Match Patch was originally built in 2006 to power Google Docs.

+
+*Compiler support: requires rustc 1.31+*
+
+<br>
+
+## Interface
+
+Here is the entire API of the Rust implementation. It operates on borrowed
+strings and the return value of the diff algorithm is a vector of chunks
+pointing into slices of those input strings.
+
+```rust
+pub enum Chunk<'a> {
+    Equal(&'a str),
+    Delete(&'a str),
+    Insert(&'a str),
+}
+
+pub fn diff(text1: &str, text2: &str) -> Vec<Chunk>;
+```
+

+
+## License
+
+The diff algorithm in this crate was ported to Rust using the Java and C++
+implementations found at <https://github.com/google/diff-match-patch> as
+reference, and is made available here under the <a href="LICENSE-APACHE">Apache
+License, Version 2.0</a> matching the license of the original. This entire
+project, including some parts unmodified from upstream and the Rust-specific
+modifications introduced in the course of porting the implementation, are
+distributed under this Apache license.
+
+Intellectual property that is unique to the Rust implementation is additionally
+made available to you dually under the <a href="LICENSE-MIT">MIT license</a>, if
+you prefer. This applies to all design choices and implementation choices not
+found in the upstream repo.
+
+Unless you explicitly state otherwise, any contribution intentionally submitted
+for inclusion in this crate by you, as defined in the Apache-2.0 license, shall
+be dual Apache and MIT licensed, without any additional terms or conditions.
