+Kernel files structure
+-----------------------
+
+Kernel for a VM is stored in `/var/lib/qubes/vm-kernels/KERNEL_VERSION` directory (`KERNEL_VERSION` replaced with actual version). Qubes supports the following files there:
+
+- `vmlinuz` - kernel binary (may not be a Linux kernel)
+- `initramfs` - initramfs for the kernel to load
+- `modules.img` - ext4 filesystem image containing Linux kernel modules (to be mounted at `/lib/modules`); additionally it should contain a copy of `vmlinuz` and `initramfs` in its root directory (for loading by qemu inside stubdomain)
+- `default-kernelopts.txt` - default kernel options, in addition to those specified with `kernelopts` VM property
+
+All the files besides `vmlinuz` are optional.
+
 Using kernel installed in the VM (R4.0)

+Accessing installer Rescue mode on UEFI
+---------------------------------------

+In UEFI mode installer do not have boot menu, but starts directly the installation wizard. To get into Rescue mode, you need to switch to tty2 (Ctrl+Alt+F2) and then execute:
