-This project demonstrates compiling Python (`_compiled.py`) and Cython (`_native.pyx`)
-modules with Hatchling and hatch-cython. CI builds native wheels for Linux x86_64,
-Linux ARM64, macOS ARM64, and Windows x86_64.
+## Overview
 
-See [How to build and test extensions](docs/development.md) for local development,
-compilation targets, and distribution checks.
+> [!NOTE]
+> This library was generated using [copier](https://copier.readthedocs.io/en/stable/) from the [Base Python Project Template repository](https://github.com/python-project-templates/base).
 
-Generated with [Copier](https://copier.readthedocs.io/en/stable/) from the
-[Cython variant of the base template](https://github.com/python-project-templates/base).
+The examples compile Python (`_compiled.py`) and Cython (`_native.pyx`) modules with hatch-cython.
+See the [development guide](docs/development.md) for build and test instructions.
