+# Contributing to `pyslang`
+
+Pyslang, the Python bindings for the [slang project](https://github.com/MikePopoloski/slang), are built, tested, and packaged with code in this repository.
+
+The bulk of functional code is in the [`slang` repository](https://github.com/MikePopoloski/slang). Please refer to its [CONTRIBUTING.md](https://github.com/MikePopoloski/slang/blob/master/CONTRIBUTING.md) guide for more information on contributing to the core project.
+
+## Python Bindings
+
+Python bindings are built using [pybind11](https://github.com/pybind/pybind11).
+
+## Documentation
+
+All documentation is contained in the `docs` directory of the `slang` repository.
+
+## Building and Testing
+
+1. Clone the `pyslang` repository (https://github.com/MikePopoloski/pyslang)
+2. Clone the `slang` submodule:
+
+```bash
+git submodule update --init --recursive
+```
+
+3. Optionally, create a virtual environment and activate it.
+
+```bash
+python3 -m venv venv
+source venv/bin/activate
+```
+
+4. Install `pyslang` as a Python package (including building the C++ `slang` library with bindings, from the submodule):
+
+```bash
+pip install .
+```
