+# UniFFI - a multi-language bindings generator for Rust
+
+UniFFI is a toolkit for building cross-platform software components in Rust.
+
+For the impatient, see [**the UniFFI user guide**](https://mozilla.github.io/uniffi-rs/)
+or [**the UniFFI examples**](https://github.com/mozilla/uniffi-rs/tree/main/examples#example-uniffi-components).
+
+By writing your core business logic in Rust and describing its interface in an "object model",
+you can use UniFFI to help you:
+
+* Compile your Rust code into a shared library for use on different target platforms.
+* Generate bindings to load and use the library from different target languages.
+
+You can describe your object model in an [interface definition file](https://mozilla.github.io/uniffi-rs/udl_file_spec.html)
+or [by using proc-macros](https://mozilla.github.io/uniffi-rs/proc_macro/index.html).
+
+UniFFI is currently used extensively by Mozilla in Firefox mobile and desktop browsers;
+written once in Rust, auto-generated bindings allow that functionality to be called
+from both Kotlin (for Android apps) and Swift (for iOS apps).
+It also has a growing community of users shipping various cool things to many users.
+
+UniFFI comes with support for **Kotlin**, **Swift**, **Python** and **Ruby** with 3rd party bindings available for **C#** and **Golang**.
+Additional foreign language bindings can be developed externally and we welcome contributions to list them here.
+See [Third-party foreign language bindings](#third-party-foreign-language-bindings).
+
+## User Guide
+
+You can read more about using the tool in [**the UniFFI user guide**](https://mozilla.github.io/uniffi-rs/).
+
+We consider it ready for production use, but UniFFI is a long way from a 1.0 release with lots of internal work still going on.
+We try hard to avoid breaking simple consumers, but more advanced things might break as you upgrade over time.
+
+### Etymology and Pronunciation
+
+ˈjuːnɪfaɪ. Pronounced to rhyme with "unify".
+
+A portmanteau word that also puns with "unify", to signify the joining of one codebase accessed from many languages.
+
+uni - [Latin ūni-, from ūnus, one]
+FFI - [Abbreviation, Foreign Function Interface]
+
+## Alternative tools
+
+Other tools we know of which try and solve a similarly shaped problem are:
+
+* [Diplomat](https://github.com/rust-diplomat/diplomat/) - see our [writeup of
+  the different approach taken by that tool](docs/diplomat-and-macros.md)
+* [Interoptopus](https://github.com/ralfbiedert/interoptopus/)
+
+(Please open a PR if you think other tools should be listed!)
+
+## Third-party foreign language bindings
+
+* [Kotlin Multiplatform support](https://gitlab.com/trixnity/uniffi-kotlin-multiplatform-bindings). The repository contains Kotlin Multiplatform bindings generation for UniFFI, letting you target both JVM and Native.
+* [Go bindings](https://github.com/NordSecurity/uniffi-bindgen-go)
+* [C# bindings](https://github.com/NordSecurity/uniffi-bindgen-cs)
+* [Dart bindings](https://github.com/NiallBunting/uniffi-rs-dart)
+
+### External resources
+
+There are a few third-party resources that make it easier to work with UniFFI:
+
+* [Plugin support for `.udl` files](https://github.com/Lonami/uniffi-dl) for the IDEA platform ([*uniffi-dl* in the JetBrains marketplace](https://plugins.jetbrains.com/plugin/20527-uniffi-dl)). It provides syntax highlighting, code folding, code completion, reference resolution and navigation (among others features) for the [UniFFI Definition Language (UDL)](https://mozilla.github.io/uniffi-rs/).
+* [cargo swift](https://github.com/antoniusnaumann/cargo-swift), a cargo plugin to build a Swift Package from Rust code. It provides an init command for setting up a UniFFI crate and a package command for building a Swift package from Rust code - without the need for additional configuration or build scripts.
+* [Cargo NDK Gradle Plugin](https://github.com/willir/cargo-ndk-android-gradle) allows you to build Rust code using [`cargo-ndk`](https://github.com/bbqsrc/cargo-ndk), which generally makes Android library builds less painful.
+* [`uniffi-starter`](https://github.com/ianthetechie/uniffi-starter) is a minimal project demonstrates a wide range of UniFFI in a complete project in a compact manner. It includes a full Android library build process, an XCFramework generation script, and example Swift package structure.
