+# Cross-Arch Testing Containers
+
+This directory containers dockerfiles that can be used in the CI to test the
+python package in non-native machine architectures, e.g., `aarch64`.
+
+The dockerfiles here 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.

+##  Cross-Arch Testing
+
+This project has built-in support for testing across multiple architectures. Currently, our CI conducts tests on `aarch64` machines using QEMU emulation. We also have the flexibility to expand this support to include additional architectures in the future. For more information, see [Cross-Arch Testing](.github/containers/nox-cross-arch/README.md).

 - A new class `Fuse` has been added to represent fuses. This class has a member variable `max_current` which represents the maximum current that can course through the fuse. If the current flowing through a fuse is greater than this limit, then the fuse will break the circuit.
 
+- The CI now runs cross-arch tests on `aarch64` architectures.
