+## Running an example simulation (Arm)
+
+Download the prebuilt bootloader and Linux Kernel with embedded initramfs
and
+extract them under the $M5_PATH directory (make sure M5_PATH points to a
valid
+directory):
+
+```sh
+wget http://dist.gem5.org/dist/v21-1/arm/aarch-system-20210904.tar.bz2
+tar -xf aarch-system-20210904.tar.bz2
+
+# copying bootloaders
+cp binaries/boot* $M5_PATH/binaries/
+
+# copying Linux Kernel
+cp binaries/vmlinux_exit.arm64 $M5_PATH/binaries/
+```
+
+`vmlinux_exit.arm64` contains an m5 binary, and `m5 exit` will be called
upon
+the booting process reaching the early userspace.
+
+Run the simulation:
+
+```sh
+sst sst/arm_example.py
+```
+
## Notes
- SwapReq from gem5 requires reading from memory and writing to memory.
