+Building/Running container for a different architecture
+-------------------------------------------------------
+
+On a x86 host, it is possible to build and run containers for other arch (like
+running a container made for Arm) with docker taking care of running the
+appropriate software to emulate that arch. For this, simply install the package
+`qemu-user-static`, and that's it. Then you can start an Arm container on x86
+host like you would start an x86 container.

+If that doesn't work, you might find some information on

I didn't see the for-4.17 tag in the title but I assume you want this
patch to go into the release since I am in the CC. Since this is a pure doc
change and everyone can be benefited from this, so if this patch is
acked/reviewed by CI maintainers, feel free to add my:

Kind regards,
