-Then, before, doing `kvmx up`, do something like the following example:
+    kvmx install <project-name> ~/path/to/install.iso
 
-    # Create the environment
-    kvmx init <guest> /var/cache/qemu/<guest>
-    qemu-img create -f qcow2 /var/cache/qemu/<guest>box.img 10G

-    # Install the Operating System
-    kvm -m 2048 -net nic,model=virtio -net user -drive file=/var/cache/qemu/<guest>/box.img -cdrom ~/path/to/install.iso
