+[![Build Status][travis_ci_badge]][travis_ci] [![Latest Version]][crates.io] [![docs]][docs.rs]
+
+A Rust interface to the **user-space** API of the Mach 3.0 kernel exposed in
+`/usr/include/mach` that underlies macOS and is linked via `libSystem` (and
+`libsystem_kernel`).
+
+This library does not expose the **kernel-space** API of the Mach 3.0 kernel
+exposed in
+`SDK/System/Library/Frameworks/Kernel.framework/Versions/A/Headers/mach`.
+
+That is, if you are writing a kernel-resident device drivers or some other
+kernel extensions you have to use something else. The user-space kernel API is
+often API-incompatible with the kernel space one, and even in the cases where
+they match, they are sometimes ABI incompatible such that using this library
+would have **undefined behavior**.
+
+# Usage
+
+Add the following to your `Cargo.toml` to conditionally include mach on those
+platforms that support it.
+
+```toml
+[target.'cfg(any(target_os = "macos", target_os = "ios"))'.dependencies.mach]
+version = "0.3"
+```
+
+The following crate features are available:
+
+* **deprecated** (disabled by default): exposes deprecated APIs that have been
+ removed from the latest versions of the MacOS SDKs. The behavior of using
+ these APIs on MacOS versions that do not support them is undefined (hopefully
+ a linker error).
+
+# Platform support
+
+The following table describes the current CI set-up:
+
+| Target | Min. Rust | XCode | build | ctest | run |
+|-----------------------|-----------|---------------|-------|-------|-----|
+| `x86_64-apple-darwin` | 1.33.0 | 6.4 - 10.0 | ✓ | ✓ | ✓ |
+| `i686-apple-darwin` | 1.33.0 | 6.4 - 10.0 | ✓ | ✓ | ✓ |
+| `i386-apple-ios` | 1.33.0 | 6.4 - 9.4 [0] | ✓ | - | - |
+| `x86_64-apple-ios` | 1.33.0 | 6.4 - 10.0 | ✓ | - | - |
+| `armv7-apple-ios` | nightly | 6.4 - 10.0 | ✓ | - | - |
+| `aarch64-apple-ios` | nightly | 6.4 - 10.0 | ✓ | - | - |
+
+[0] `i386-apple-ios` is deprecated in XCode 10.0.
