+##  Cross-Arch Testing
+
+This project has built-in support for testing across multiple architectures.
+Currently, our CI conducts tests on `arm64` machines using QEMU emulation. We
+also have the flexibility to expand this support to include additional
+architectures in the future.
+
+This project contains Dockerfiles that can be used in the CI to test the
+python package in non-native machine architectures, e.g., `arm64`. The
+Dockerfiles exist in the directory `.github/containers/nox-cross-arch`, and
+follow a naming scheme so that they can be easily used in build matrices in the
+CI, in `nox-cross-arch` job. The naming scheme is:
+
+```
+<arch>-<os>-python-<python-version>.Dockerfile
+```
+
+E.g.,
+
+```
+arm64-ubuntu-20.04-python-3.11.Dockerfile
+```
+
+If a Dockerfile for your desired target architecture, OS, and python version
+does not exist here, please add one before proceeding to add your options to
+the test matrix.
