+# `arm64e-apple-tvos`
+
+**Tier: 3**
+
+ARM64e tvOS (10.0+)
+
+## Target maintainers
+
+- Artyom Tetyukhin ([@arttet](https://github.com/https://github.com/arttet))
+
+## Requirements
+
+This target is cross-compiled and supports `std`.
+To build this target Xcode 12 or higher on macOS is required.
+
+## Building the target
+
+You can build Rust with support for the targets by adding it to the `target` list in `config.toml`:
+
+```toml
+[build]
+target = [ "arm64e-apple-tvos" ]
+```
+
+## Building Rust programs
+
+Rust does not yet ship pre-compiled artifacts for this target.
+To compile for this target, you will need to build Rust with the target enabled (see [Building the target](#building-the-target) above).
+
+## Testing
+
+The target does support running binaries on tvOS platforms with `arm64e` architecture.
+
+## Cross-compilation toolchains and C code
+
+The targets do support `C` code.
+To build compatible `C` code, you have to use XCode with the same compiler and flags.
