+# Qemu helper
+
+Can be used with the `mkosi` test tooling
+
+After `mkosi -B build` has been executed, run the following:
+
+    python test_tooling/qemu/qemu.py \
+        --uki ./test_tooling/mkosi/mkosi.output/image_13.efi \
+        --harddrive ~/test.qcow2:15G \
+        --harddrive ~/test_large.qcow2:25G
+
+And install using `archinstall`, after the machine has been shutdown, run:
+
+    python test_tooling/qemu/qemu.py \
+        --harddrive ~/test.qcow2:15G \
+        --harddrive ~/test_large.qcow2:25G
+
+As this will boot EFI mode with just the harddrives to verify the installation.
