+** Fresh system (nixos USB drive)
+
+1. Open a nix-shell with git:
+> nix-shell -p git
+
+2. Clone the flake
+> git clone https://git.lajuntament.space/marc/samfelag.git
+
+3. Partition the disk
+
+3.0 Locate the disk
+> lsblk
+
+3.1 Create the partition table
+You can use GParted or fdisk (example of the latter):
+> sudo fdisk <<device: e.g /dev/nvme0n1>>
+
+> Command (m for help): g
+Created a new GPT disklabel (GUID: CF653F38-902C-0648-B8AF-B4E07A8E0E8C).

+> Command (m for help): n
+> Partition number (1-128, default 1):

+> Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-2000409230, default 2000409230): +512M
+Created a new partition 1 of type 'Linux filesystem' and of size 512 MiB.
+
+> Command (m for help): t
+Selected partition 1
+> Partition type or alias (type L to list all): 1
+Changed type of partition 'Linux filesystem' to 'EFI System'.
+
+> Command (m for help): n

+The partition table has been altered.
+Calling ioctl() to re-read partition table.
+Syncing disks.
+
+3.1 Create the boot partition
+> sudo mkfs.fat -F 32 <<device: e.g. /dev/nvme0n1p1>>
+> sudo fatlabel /dev/nvme0n1p1 BOOT
+
+3.2 Create the root partition
+> sudo mkfs.ext4 <<device: e.g. /dev/nvme0n1p2>> -L nixos
+
+3.3 Create the swap partition
+> sudo mkswap <<device: e.g. /dev/nvme0n1p3>> -L swap
+
+4. Create the host nix configuration
+If the host is not present under system/hosts, create a new folder for the host.
+Generate the hardware configuration file, you can use nixos-generate-config as a base:
+
+> nixos-generate-config --dir <<host directory>> --no-filesystems
