-## OS template
-
 You will need a working OS template to work with this project.
 
 Easy solution create an OS template:
-- start any archlinux machine (the arch installer also works)
+- mount the archlinux installation .iso in a VM
-- install `arch-install-scripts`
+- run `pacstrap /mnt base linux openssh`
-- run `pacstrap /mnt base openssh` to install base packages to /mnt
 - run `ln -s /usr/lib/systemd/system/sshd.service /mnt/etc/systemd/system/multi-user.target.wants/sshd.service`
-- run `fsarchiver savedir /tmp/os_template.fsa /mnt` to save your OS template
+- run `fsarchiver savedir /tmp/os_template.fsa /mnt`
-- download `/tmp/os_template.fsa` to your machine
+- download `/tmp/os_template.fsa`
 - upload the `os_template.fsa` anywhere so that it can be downloaded with wget
 
 Some notes on the above:
-- base is the only package required to run a dtrfs VM; the kernel is not needed cause we are using SNP
+- base and linux are the only packages to run a VM
 - you will need sshd to operate the VM, so create the symlink to make it start with the OS
 - fsarchiver is very good at preserving OS data
-- fsarchiver saves the absolute path (which means you must use `/mnt` as this is hardcoded)
 - the initrd will dump that template to the encrypted disk
 - the same procedure can be used with any distribution, but we didn't test that yet
 
-## initrd and linux
-
-You will need an initrd and a kernel to run SNP VMs.
-
-- start any archlinux machine
-- clone this repo
-- inspect your kernel version by running `file -sL /boot/vmlinuz-linux`.
-- (optional) update the kernel version in `./creator_exports.sh`
-- create the initrd by running `./create.sh`; this will save the initrd in the build folder
-- grab your kernel from `/boot/vmlinuz-linux` and...
-- ... upload kernel and initrd to your hypervizor
-
-## module scanner
-
-Optionally, you can use `./remote_create.sh` to upload this repo to remote node and build your initrd.
-This will automatically scan the kernel modules running on the remote host, and package all modules in the initrd. This is ideal if your VM has a setup that is not cover by the modules hardcoded in this repo.
