+# aarch64-nintendo-switch-freestanding
+
+**Tier: 3**
+
+Nintendo Switch with pure-Rust toolchain.
+
+## Designated Developers
+
+* [@leo60228](https://github.com/leo60228)
+* [@jam1garner](https://github.com/jam1garner)
+
+## Requirements
+
+This target is cross-compiled.
+It has no special requirements for the host.
+
+## Building
+
+The target can be built by enabling it for a `rustc` build:
+
+```toml
+[build]
+build-stage = 1
+target = ["aarch64-nintendo-switch-freestanding"]
+```
+
+## Cross-compilation
+
+This target can be cross-compiled from any host.
+
+## Testing
+
+Currently there is no support to run the rustc test suite for this target.
+
+## Building Rust programs
+
+If `rustc` has support for that target and the library artifacts are available,
+then Rust programs can be built for that target:
+
+```text
+rustc --target aarch64-nintendo-switch-freestanding your-code.rs
+```
+
+To generate binaries in the NRO format that can be easily run on-device, you
+can use [cargo-nx](https://github.com/aarch64-switch-rs/cargo-nx):
+
+```text
+cargo nx --triple=aarch64-nintendo-switch-freestanding
+```
