+> Note: `lsblk` may additionally show `/nix/store` as a mountpoint on `lvmroot-root`. This is not a separate partition. NixOS mounts the root device a second time at `/nix/store` with `ro,nosuid,nodev` flags to enforce store immutability at runtime.
+
+2. prepare the installation
+```bash
+# format the boot partition
+mkfs.fat -F 32 /dev/nvme0n1p1 -n "nixboot"
+# create an encrypted partition
+cryptsetup luksFormat -y --label="nixcrypt" /dev/nvme0n1p2
+# open the encrypted partition and map it to /dev/mapper/cryptroot
+cryptsetup luksOpen /dev/nvme0n1p2 cryptroot
+
+# create the physical volume
+pvcreate /dev/mapper/cryptroot
+# create a volume group inside
+vgcreate lvmroot /dev/mapper/cryptroot
+# create the swap volume
+lvcreate --size 8G lvmroot --name swap
+# if you desire, create a home volume
+lvcreate --size 150G lvmroot --name home
+# create the root volume
+lvcreate -l 100%FREE lvmroot --name root
+
+# format as usual for root partition
+mkfs.ext4 -L "nixroot" /dev/mapper/lvmroot-root
+# if you previously made the home partition, do it too
+mkfs.ext4 -L "nixhome" /dev/mapper/lvmroot-home
+# format the swap partition
+mkswap -L "nixswap" /dev/mapper/lvmroot-swap
+
+# mount root
+mount /dev/disk/by-label/nixroot /mnt
+# mount boot
+mount --mkdir /dev/nvme0n1p1 /mnt/boot
+# again, if you did the home volume
+mount --mkdir /dev/disk/by-label/nixhome /mnt/home
+# turn on swap
+swapon /dev/disk/by-label/nixswap
+```
+
+3. prepare nixos
+```bash
+# generate templates and update the hardware-configuration.nix
+nixos-generate-config --root /mnt
+
+# add dm-crypt and dm-mod to the kernelModules
+boot.initrd.kernelModules = [ "dm-crypt" "dm-mod" ];
+
+# add file systems using labels
+fileSystems."/" =
+  { device = "/dev/disk/by-label/nixroot";
+    fsType = "ext4";
+  };
+fileSystems."/boot" =
+  { device = "/dev/disk/by-label/nixboot";
+    fsType = "vfat";
+    options = [ "fmask=0022" "dmask=0022" ];
+  };
+fileSystems."/home" =
+  { device = "/dev/disk/by-label/nixhome";
+    fsType = "ext4";
+  };
+swapDevices =
+  [ { device = "/dev/disk/by-label/nixswap"; }
+  ];
+
+# point the bootloader to the luks device
+boot.initrd.luks.devices."cryptroot".device = "/dev/disk/by-label/nixcrypt";
+```
+
+4. install nixos
+```bash
+nixos-install
+```
+
+## how to deploy the initial config
+- Don't forget to install the bootloader, if you changed it since `nixos-install`
+```bash
+$ sudo nixos-rebuild --install-bootloader switch --flake .#host_name
+```
+
+## how to upgrade the system
+```bash
+$ cd /path/to/repo
+$ nix flake update
+$ sudo nixos-rebuild switch --flake .#host_name
+$ sudo nix-collect-garbage
+```
+
+## how to use nix-helper
+
+The tool nix-helper is installed by this configuration. It simplifies administrating nixos and adds more output to the rebuild command. It also features a diff after a successful build. The command uses the `NH_FLAKE` environment variable to be able to run from whatever directory.
+
+Basic commands with a set `NH_FLAKE` variable are:
+```bash
+$ nh os switch
+$ nh os build
+$ nh os test
+$ nh clean all --keep 5
+```
+
+There is also the option to interface with home-manager by using `nh home switch` but this isn't necessary since home-manager is imported as a module in this config.
