 # Installation
+
+The first part of starting the installation is getting an install media.
+For this guide, the minimal will be assumed, and can be found [here](https://nixos.org/download/), at the bottom of the page.
+
+Booting it, you will get a TTY.
+To be able to run all the commands without any issues, please run `sudo -i` to have root privileges.
+We are then able to setup some pleasantries, such as `loadkeys sv-latin1` for a Swedish keyboard layout (Please lookup your own layout for other languages) and `setfont ter-v32n` for a larger font.
+
+
+If you want WIFI, run `systemctl start wpa_supplicant` and then `wpa_cli`.
+This is then followed by something like the following
+```bash
+> add_network
+0
+
+> set_network 0 ssid "myhomenetwork"
+OK
+
+> set_network 0 psk "mypassword"
+OK
+
+> enable_network 0
+OK
+
+> quit
+```
+You should now have network, if you used the right `ssid` and `psk`.
+
+It is now time to setup your disks.
+I prefer to use `cfdisk`, since it is a nice way to see all the current allocations.
+In `cfdisks` TUI, follow the following steps, for the disk that you want to partition
+- gpt
+- New 512M
+- Type (EFI System)
+- New (Size left minus amount of ram)
+- New (Rest)
+- Type (Linux Swap)
+- Write
+- Quit
+
+The disk have now been partitioned, but need to be formatted.
+To get the names of the disk you can run `lsblk`.
+In my case, when I was installing it in a VM, I was able to see that it was `vda` that was the relevant part.
+Usually, installations on hardware care about `sdx` or `nvme0nX`.
+```bash
+> lsblk
+NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINTS
+loop0    7:0    0  1.5G  1 loop /nix/.ro-store
+sr0     11:0    1  1.6G  1 rom  /iso
+sr1     11:1    1 1024M  0 loop
+vda    253:0    0   32G  0 disk
+├─vda1 253:1    0  512M  0 part
+├─vda2 253:2    0   28G  0 part
+└─vda3 253:3    0  3.5G  0 part
+```
+
+With the devices known, run the following commands.
+```bash
+> mkfs.fat -F 32 -n boot /dev/vda1
+> mkfs.ext4 -L nixos /dev/vda2
+> mkswap -L swap /dev/vda3
+```
+
+`mkfs.fat` is to make the boot disk, and ensure that it is Fat32, with the name boot.
+Similarly, `mkfs.ext4` creates the root file system, with the name nixos, and `mkswap` to create the swap.
+
+We are now able to mount the future system, using
+```bash
+> mount /dev/disk/by-label/nixos /mnt
+> mkdir -p /mnt/boot
+> mount -o umask=077 /dev/disk/by-label/boot /mnt/boot
+> swapon /dev/disk/by-label/swap
+```
+
+With the system mounted, you can install using the following
+```bash
+> nixos-generate-config --root /mnt --flake
+writing /mnt/etc/nixos/hardware-configuration.nix...
+writing /mnt/etc/nixos/flake.nix...
+writing /mnt/etc/nixos/configuration.nix...
+For more hardware-specific settings, see https://github.com/NixOS/nixos-hardware.
+> nixos-install --flake /mnt/etc/nixos/.#nixos
+...
+```
+
+With this you have an installed system, with a root user, but not much more.
+How to configure the system, to add users, software, drivers and such, will be covered in [Configuration](../configuration/index.md).
+But, you might need to understand some aspects of the nix language in order to fully understand how to do configuration, so that will be covered in [Nix basics](../nixbasics/index.md).
