+# How to install arch on the hp omen
+
+## Disk Layout
+
+We're using the following disks
+
+```
+/dev/nvme0n1 - 500GiB m.2 SSD
+/dev/sda     - 2TB SATA SSD
+```
+
+## Partitioning
+
+We're creating three partitions. One EFI, one root and one home partition.
+The root and home partition are to be encrypted with dm-crypt.
+
+```sh
+fdisk /dev/nvme0n1
+> g        # gpt partition table
+> n        
+> <Enter>  # starting from the beginning
+> +500M    # 500 MiB
+> t 1      # EFI partition
+> n        # new partition
+> <Enter>  # 
+> <Enter>  # use the remaining size of the disk
+> w        
+> q
+
+fdisk /dev/sda
+> g
+> n
+> <Enter>
+> <Enter>  # use the whole disk
+> w
+> q
+
+# Create the encrypted root partition
+cryptsetup -cipher aes-xts-plain64 --key-size 512 --hash sha512 --iter-time 5000 --use-random luksFormat /dev/nvme0n1p2
+
+# Create the encrypted home partition
+cryptsetup -cipher aes-xts-plain64 --key-size 512 --hash sha512 --iter-time 5000 --use-random luksFormat /dev/sda1
+
+# Open the devices
+cryptsetup luksOpen /dev/nvme0n1p2 cryptroot
+cryptsetup luksOpen /dev/sda1 crypthome
+
+# Create the filesystems
+mkfs.fat -F 32 /dev/nvme0n1p1
+mkfs.btrfs /dev/mapper/cryptroot
+mkfs.btrfs /dev/mapper/crypthome
+
+# mount the partitions in the correpsonding paths
+mount /dev/mapper/cryptroot /mnt
+mkdir /mnt/boot
+mount /dev/nvme0n1p1 /mnt/boot
+mkdir /mnt/home
+mount /dev/mapper/crypthome /mnt/home
+```
+
+## Pacstrap
+
+```sh
+# install base, kernels, firmware and utils
+pacstrap -i /mnt base base-devel linux linux-zen linux-firmware intel-ucode vim nushell
+```
+
+## Steps in Chroot
+
+```sh
+# enter new root
+arch-chroot /mnt
+```
+
+### Timezone and Time
+
+```sh
+# Uncomment at least one desired locale
+vim /etc/locale.gen
+locale-gen
+# Use your main locale
+echo LANG=en_GB.UTF-8 /etc/locale.conf
+export LANG=en_GB.UTF-8
+
+# Timezone info
+ln -s  /usr/share/zoneinfo/Europe/Berlin /etc/localetime
+
+# Configure hwclock to utc
+hwclock --systohc --utc
+
+# Set the keyboard layout
+echo KEYMAP=de > /etc/vconsole.conf
+```
+
+### Pacman
+
+Open `/etc/pacman.conf` and uncomment `Color` and `ParallelDownlods=5` as well
+as the section containing the `multilib` repository
+
+
+### Users
+
+```sh
+# set the root password
+passwd
+
+# Add a user (this one is called trivernis)
+useradd -m -G wheel -s /bin/nu trivernis
+
+# Change the user's password
+passwd trivernis
+
+# Enable the wheel group
+EDITOR=/bin/vim visudo # uncomment the corresponding line 
+```
+
+
+### Bootloader (systemd-boot)
+
+Add mkinitcpio hooks
+```sh
+# TODO
+```
+
+```sh
+# Generate initrds
+mkinitcpio -P
+
+bootctl install
+```
+
+Create records in /boot/loader/entries/
+
+```sh
+# arch-zen.conf
+title Arch Linux (linux-zen)
+linux /vmlinuz-linux-zen
+initrd /intel-ucode.img
+initrd /initramfs-linux-zen.img
+options cryptdevice=/dev/nvme0n1p2:cryptroot root=/dev/mapper/cryptroot zswap.enabled=1 intel_pstate=no_hwp rootfstype=btrfs
+```
+
+```sh
+# arch.conf
+title Arch Linux (linux)
+linux /vmlinuz-linux
+initrd /intel-ucode.img
+initrd /initramfs-linux.img
+options cryptdevice=/dev/nvme0n1p2:cryptroot root=/dev/mapper/cryptroot zswap.enabled=1 intel_pstate=no_hwp rootfstype=btrfs
+```
+
+```sh
+# arch-fallback.conf
+title Fallback Arch Linux (linux)
+linux /vmlinuz-linux
+initrd /intel-ucode.img
+initrd /initramfs-linux-fallback.img
+options cryptdevice=/dev/nvme0n1p2:cryptroot root=/dev/mapper/cryptroot zswap.enabled=1 intel_pstate=no_hwp rootfstype=btrfs
+```
+
+Configure the bootloader with `/boot/loader/loader.conf`
+
+```sh
+timeout 2
+default arch-zen.conf
+console-mode max
+````
+
+### Disks
+
+```sh
+# Create key for /home cryptdevice
+mkdir /etc/keys
+chmod 700 /etc/keys
+dd bs=512 count=4 if=/dev/random of=/etc/keys/crypthome.key iflag=fullblock
+chmod 600 /etc/key/crypthome.key
+cryptsetup luksAddKey /dev/sda1 /etc/keys/crypthome.key
+```
+
+Edit `/etc/cryptab` And add the device with the created key
+
+
+### Networking
+
+```sh
+# set the hostname
+echo archomen > /etc/hostname
+
+# Install the networkmanager
+pacman -S networkmanager
+systemctl enable NetworkManager.service --now
+```
+
+
+### Desktop Environment (KDE)
+
+```sh
+# Install audio support
+pacman -S pulseaudio
+
+# install KDE. Choose 
+# > noto-fonts 
+# > pipewire-jack
+# > wireplumber 
+# > phonon-qt5-gstreamer 
+# in the selection prompts
+pacman -S sddm plasma plasma-wayland-session xorg-xwayland xdg-desktop-portal-kde plasma-nm plasma-pa kwallet5 kwallet-pam kwalletmanager
+
+# Enable sddm on startup
+systemd enable sddm
+```
+
+
+### PRIME Offloading
+
+Make sure to remove `kms` from the `/etc/mkinitcpio.conf` HOOKS section
+
+```sh
+# Install nvidia drivers
+pacman -S linux-headers linux-zen-headers dkms nvidia-dkms prime nvidia-utils lib32-nvidia-utils
+```
+
+
+### Yay
+
+```sh
+pacman -S git
+git clone https://aur.archlinux.org/yay.gi
+cd yay
+makepkg -si
+```
