-Please see [Instructions for the Docker setup](docker/README.md)
+We recommend installing the wrapper from PyPI using `pip`, as this is the simplest method.
+If you prefer to build from source, you can use the [openfhe-python-packager](https://github.com/openfheorg/openfhe-python-packager) on Linux or follow the build instructions below. The packager generates a wheel that can be installed with `pip`.
 
-## Building from Source
+The legacy build instructions below are for other operating systems where [openfhe-python-packager](https://github.com/openfheorg/openfhe-python-packager) may not work.
 
 ### Requirements
 
 Before building, make sure you have the following dependencies installed:
 
-- [OpenFHE 1.4.0+](https://github.com/openfheorg/openfhe-development) by following the instructions in [OpenFHE Documentation](https://openfhe-development.readthedocs.io/en/latest/sphinx_rsts/intro/installation/installation.html)
-- [Python 3.6+](https://www.python.org/)
+- [OpenFHE 1.4.1+](https://github.com/openfheorg/openfhe-development) by following the instructions in [OpenFHE Documentation](https://openfhe-development.readthedocs.io/en/latest/sphinx_rsts/intro/installation/installation.html)
+- [Python 3.10+](https://www.python.org/)
 - [pybind11](https://pybind11.readthedocs.io/en/stable/installing.html)
 
 We recommend following OpenFHE C++ installation instructions first (which covers Linux, Windows and MacOS) and then getting back to this repo. See notes on installing `pybind11` below
