+[![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:

+
+[![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 = "0.4"
+```
+
+Available crate feature:
+
+* **unstable** (disabled by default): Exposes newly changed APIs. Enabling this may
+  bring breaking changes (see the breaking change policy).
+
+
+### Breaking change policy
+
+We do the following steps when an item is changed/removed on latest toolchain:
+
+1. Deprecate an existing one
+2. Declare a new one under the `unstable` feature
+3. After a month or more since releasing a new version that contains that change,
+  remove/change an older one
+
+For instance, if const `FOO` value is changed from `3` to `4`,
+we expose the newer one, i.e. `4`, under `unstable` first.
+So the `unstable` users should notice the change on the first release since deprecating.
+After a month or more, all the users should notice it.
+
+## Platform support
+
+The following table describes the current CI set-up:
+
+| Target                  | Min. Rust | XCode           | build | ctest | run |
+|-------------------------|-----------|-----------------|-------|-------|-----|
