+# Wheel builds for typed_python
+
+Using [Manylinux](https://github.com/pypa/manylinux) we can make typed_python
+more portable.
+
+## Building wheels
+
+1. Prerequisites: docker
+2. Run `run_build.sh <python_version>` (37 38 39 310 are supported)
+
+This process should create a `./wheels` directory under the typed_python repo
+root with wheels for python 3.7-3.10 built for linux x86_64 that are uploadable
+to pypi
+
+## Release to pypi
+
+1. pip install twine
+2. twine upload wheels/*.whl
+
+## Notes
+
+Here we're using the CentOS 7 based manylinux2014 image. 
+We cannot move to the newer `manylinux_x_y` image ([PEP 600](https://peps.python.org/pep-0600/)) 
+until type_python drops support for python 3.7
+
+`typed_python` code does not build on arm64 though manylinux does support it.
