+# UniFFI Starter
+
+This is a simple, mostly minimal, but more-complex-than-just-addition
+demonstration of how to use [UniFFI](https://github.com/mozilla/uniffi-rs)
+in a structure that works for MOST use cases.
+
+The project has a Rust core, a Swift Package, and a Gradle project
+in a structure that I've found to be fairly general.
+The goal is for you to fork this as as starter to get past the boilerplate
+and get started writing your cross-platform library.
+
+## Motivating use case
+
+As promised, it's more complex than addition, but it's intentionally
+a bit ridiculous to keep things fun and demonstrate a wide range of uses
+in a small project.
+I say small, but note that the vast majority is boilerplate
+Read on for a guide to the "good parts".
+
+We're building a "safe" calculator that can do integer arithmetic.
+(The usual demostrations of just addition are not complex enough to be very useful.)
+The Rust core will provide addition and division operators.
+The native code will show you how to supply your OWN operators written in Swift and Kotlin.
+Because nobody knows where math is going next,
+this OBVIOUSLY needs to be completely extensible with new operators ;)
+
+By "safe" of course I mean that on the Rust side, everything returns a result,
+which is translated into exceptions for iOS and Android.
+At least you'll get a clean exception from Rust to let you know
+about your integer overflows and division by zero!
+
+Now if this is all starting to sound like every other over-engineered (read: ruined) 
+Java project, it definitely is, but I hope it's useful
+in showing a wide range of examples in an easy-to-understand project.
+
+This demonstration library also embraces the
+functional core/imperative shell architecture.
+Jokes about over-engineering aside,
+while this is total overkill for a calculator app,
+you really SHOULD strongly consider using this pattern
+for any non-trivial real-world library.
+
+Hope this helps!
+
+## Quick start
+
+### Rust
+
+Open up the project in your favorite editor and poke around the Cargo workspace
+under `rust/`!
+
+#### Stuff to look at 
+
+* All of the code is in `foobar/src/lib.rs`, including several unit tests
+to demonstrate the Rust API.
+* Also check `Cargo.toml` and the overall workspace structure to see how a UniFFI project needs to be structured on the Rust side.
+* Check out `rust-toolchain.toml`; **if you aren't using `rustup`, this is your checklist of toolchains to install!**
+
+### iOS
+
+Before opening up the Swift package in Xcode, you need to build the Rust core.
+
+```shell
+cd rust/
+./build-ios.sh
+```
+
+This generates an XCFramework and generates Swift bindings to the Rust core.
+Check the script if you're interested in the gritty details.
+
+**You need to do this every time you make Rust changes that you want reflected in the Swift Package!**
+
+#### Stuff to look at
+
+* `Package.swift` documents the UniFFI setup (which is... special thanks to SPM quirks).
+* `SafeCalculator` and `SafeMultiply` in `Sources/Foobar` contain the Swift-y calculator wrapper class and multiplication operator.
+* The unit tests in `Tests/FoobarTests/SafeCalculatorTests.swift` demonstrate usage.
+
+### Android
+
+Android is pretty easy to get rolling, and Gradle will build everything for you
+after you get a few things set up.
+Most importantly, you need to install [`cargo-ndk`](https://github.com/bbqsrc/cargo-ndk).
+
+```shell
+cargo install cargo-ndk
+```
+
+If you've tried building the Rust library already and you have rustup,
+the requisite targets will probably be installed automatically.
+If not, follow the steps in the [`cargo-ndk` README](https://github.com/bbqsrc/cargo-ndk)
+to install the required Android targets.
+
+Just open up the `android` project in Android Studio and you're good to go.
+It took forever to get the tooling right, but now that it's there, it just works.
+Note that the app target is intentionally super barebones;
+it's only there to illustrate how Gradle project dependencies work within a single workspace.
+
+#### Stuff to look at
+
+* The interesting stuff lives under the `SafeCalculator` and `SafeMultiply` classes.
+* Also check out the tests for an example of usage.
+* You can also check out the Android tests.
+* The gradle files are mostly boilerplate, but there are a few things in there needed for building the Rust library. That took a while to figure out, and I currently believe this is the easiest approach.
+
+## Learning more
+
+Obviously, UniFFI's GitHub is probably the best place to learn more and ask questions.
+If you're interested in following a slightly more serious dev log about using UniFFI
+in a real library, check out the following:

+* [Ferrostar on GitHub](https://github.com/stadiamaps/ferrostar) - a next gen navigation SDK I'm developing along with @Archdoog.
