+nlwpy
+==============
+
+An example project built with [pybind11](https://github.com/pybind/pybind11).
+This requires Python 3.7+; for older versions of Python, check the commit
+history.
+
+Installation
+------------
+
+ - clone this repository
+ - `pip install ./nlwpy [--prefix=.]`
+
+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`][]. You can also see a basic recipe for building and
+testing in `pip.yml`, and `conda.yml` has an example of a conda recipe build.
+
+
+Building the documentation
+--------------------------
+
+Documentation for the example project is generated using Sphinx. Sphinx has the
+ability to automatically inspect the signatures and documentation strings in
+the extension module to generate beautiful documentation in a variety formats.
+The following command generates HTML-based reference documentation; for other
+formats please refer to the Sphinx manual:
+
+ - `cd python_example/docs`
+ - `make html`
+
+License

+
+Test call
+---------
+
+Inline:
+
+```python
+import nlwpy as m
+m.add(1, 2)
+```
+
+Use tests:
+
+```bash
+[PYTHONPATH=./<installation path++>] python test.py
+```
