-Installation
-------------
+## Installation
 
-- clone this repository
+- Clone this repository
 - `pip install ./scikit_build_example`
 
+## Test call
+
+```python
+import scikit_build_example
+
+scikit_build_example.add(1, 2)
+```
+
+## Files
+
+This example has several files that are a good idea, but aren't strictly
+necessary. The necessary files are:
+
+* `pyproject.toml`: The Python project file
+* `CMakeLists.txt`: The CMake configuration file
+* `src/main.cpp`: The source file for the C++ build
+* `src/scikit_build_example/__init__.py`: The Python portion of the module. The root of the module needs to be `<package_name>`, `src/<package_name>`, or `python/<package_name>` to be auto-discovered.
+
+These files are also expected and highly recommended:
+
+* `.gitignore`: Git's ignore list, also used by `scikit-build-core` to select files for the SDist
+* `README.md`: The source for the PyPI description
+* `LICENSE`: The license file
 
-CI Examples
------------
+There are also several completely optional directories:
+
+* `.github`: configuration for [Dependabot][] and [GitHub Actions][]
+* `conda.recipe`: Example recipe. Normally you should submit projects to conda-forge instead of building them yourself, but this is useful for testing the example.
+* `docs/`: Documentation
+* `tests/`: Tests go here
+
+And some optional files:
+
+* `.pre-commit-config.yaml`: Configuration for the fantastic static-check runner [pre-commit][].
+* `noxfile.py`: Configuration for the [nox][] task runner, which helps make setup easier for contributors.
+
+This is a simplified version of the recommendations in the [Scientific-Python
+Development Guide][], which is a _highly_ recommended read for anyone
+interested in Python package development (Scientific or not). The guide also
+has a cookiecutter that includes scikit-build-core and pybind11 as a backend
+choice.
+
+### CI Examples
 
 There are examples for CI in `.github/workflows`. A simple way to produces
 binary "wheels" for all platforms is illustrated in the "wheels.yml" file,
-using [`cibuildwheel`][].
