 ## `setuptools-rust` integration
 
-TODO
+[`setuptools-rust`][setuptools-rust] is a setuptools helpers for Rust Python extensions. It supports `PyO3` by default.
+
+For detailed usage, please refer to its [README](https://github.com/PyO3/setuptools-rust/blob/master/README.rst)
 
 ## Source distribution
 
-TODO
+To build a source code distribution, you need to add the following lines to your `MANIFEST.in` file to ensure it correctly packages Rust extension source code.
+
+```text
+include Cargo.toml
+recursive-include src *
+```
+
+Then you can build a source code distribution by (assuming you have already written a `setup.py`):
+
+```bash
+python setup.py sdist
+```
 
 ## Binary wheel distribution
 
-TODO
+To build a binary wheel, [manylinux](https://github.com/pypa/manylinux) would be a natural choice for Linux.
+
+TODO: an manylinux1 example, macOS wheel
