 To use InstantOn during an application container image build, the host machine must satisfy the following prerequisites:
 
 - Uses the Linux Operating System with kernel version 5.9 or greater
-- Uses the X86-64/AMD64 processor architecture
+- Uses one of the following the processor architectures: X86-64/AMD64, Power (with IBM Semeru Java version 21.0.1+), Z (s390x) (with IBM Semeru Java version 21.0.1+)
 - Allows execution of privileged container builds by using Podman or Docker
 
 The use of privileged containers in the application container image build is required only when you build the container image with InstantOn. Running the resulting InstantOn application image does not require the use of privileged containers.
