 ### Supported devices and architectures
 
-As mentioned on the [Docker Hub](https://hub.docker.com/r/ppodgorsek/robot-framework), the project has been built and uploaded as a `linux/amd64` image. This means ARM devices won't be able to run the image with the default configuration.
+As mentioned on the [Docker Hub](https://hub.docker.com/r/ppodgorsek/robot-framework), the project has been built and uploaded as a `linux/amd64` image only. This means ARM devices such as MacBook M1/M2 and Amazon EC2 Graviton won't be able to run the image with the default configuration.

+As mentioned in the official documentation, [Podman](https://docs.podman.io/en/latest/markdown/podman-run.1.html#platform-os-arch) and [Docker](https://docs.docker.com/build/building/multi-platform/) provide a `--platform` option which selects a given application architecture, such as:
 
     docker run \
         --platform linux/amd64 \
         -v <local path to the reports' folder>:/opt/robotframework/reports:Z \
         -v <local path to the test suites' folder>:/opt/robotframework/tests:Z \
         ppodgorsek/robot-framework:<version>
 
-Please note: such emulation might not work, depending on your device and operating system.
+Please note: builds and automated tests of this project will remain performed on a `linux/amd64` architecture so such emulation might not work, depending on your device and operating system.
 
-If this does not solve your platform-related issues, you will have to rebuild the image for your device/platform.
+If this does not solve your platform-related issues, you will have to rebuild the image for your device/platform, specifying that `--platform` option during the build and run.
