+
+## Requirements
+
+Building the target itself requires a 64-bit little endian PowerPC compiler that is supported by `cc-rs`.
+
+## Building the target
+
+The target can be built by enabling it for a `rustc` build.
+
+```toml
+[build]
+target = ["powerpc64le-unknown-linux-gnu"]
+```
+
+Make sure your C compiler is included in `$PATH`, then add it to the `config.toml`:
+
+```toml
+[target.powerpc64le-unknown-linux-gnu]
+cc = "powerpc64le-linux-gnu-gcc"
+cxx = "powerpc64le-linux-gnu-g++"
+ar = "powerpc64le-linux-gnu-ar"
+linker = "powerpc64le-linux-gnu-gcc"
+```
+
+## Building Rust programs
+
+This target is distributed through `rustup`, and requires no special
+configuration.
+
+## Cross-compilation
+
+This target can be cross-compiled from any host.
+
+## Testing
+
+This target can be tested as normal with `x.py` on a 64-bit little endian
+PowerPC host or via QEMU emulation.
