+# ff2mpv-rust
+
+</div>
+
+Native messaging host for ff2mpv written in Rust.
+
+This is a native compiled binary, so it runs much faster and doesn't require external dependencies by itself, unlike Python and Ruby scripts.
+
+# What is this?
+This is a script for hooking mpv and [ff2mpv](https://github.com/woodruffw/ff2mpv), that allows opening any video link in mpv straight from the browser.
+
+# Contributing
+
+All issues and pull requests are welcome! Feel free to open an issue if you've got an idea or a problem. You can open a pull request if you are able to implement it yourself.
