# Installation
-In the near future, `std::autodiff` should become available for users via rustup.
-As a rustc/enzyme/autodiff contributor however, you will still need to build rustc from source.
-For the meantime, you can download up-to-date builds to enable `std::autodiff` on your latest nightly toolchain, if you are using either of:
-**Linux**, with `x86_64-unknown-linux-gnu` or `aarch64-unknown-linux-gnu`
-**Windows**, with `x86_64-llvm-mingw` or `aarch64-llvm-mingw`
+Most users can enable `std::autodiff` on their latest nightly toolchain by installing the `enzyme` component with rustup, if they are using one of these platforms:
-In the past you could also download builds for **Apple** (aarch64-apple), however they are not usable at the moment.
+- **Linux**: with `x86_64-unknown-linux-gnu` or `aarch64-unknown-linux-gnu`
+- **macOS**: with `aarch64-apple-darwin`
+- **Windows**: with `x86_64-llvm-mingw` or `aarch64-llvm-mingw`
-If you need any other platform, you can build rustc including autodiff from source.
-Please open an issue if you want to help enabling automatic builds for your prefered target.

## Installation guide
-If you want to use `std::autodiff` on Linux or Windows and don't plan to contribute PR's to the project, then we recommend to just use your existing nightly installation and download the missing component. Please run:

-Apple support was temporarily reverted, due to downstream breakages. Please build it from source till we can re-enable it.
