+Install Arch Linux
+==================
+
+This is my personal setup almost every time I install Arch Linux.
+This is meant for me as being something I can quickly reference.
+
+Change localkeys to my keyboard layout
+--------------------------------------
+
+In my case I have a Danish keyboard layout.
+
+```bash
+loadkeys dk
+```
+
+You can find your keymap file by using localectl:
+
+```bash
+localectl list-keymaps
+```
+
+Or by simply looking inside the /usr/share/kbd/keymaps/ directory.
+
+```bash
+find /usr/share/kbd/keymaps/ -type f
+```
+
+Create Partitions
+-----------------
+
+```bash
+cfdisk
+```
+
+Set up the partions, mount and use swap
+---------------------------------------
+
+Let us say you have a simple setup:
+
+- /boot partition (ext2)
+- /     partition (ext4)
+- /home partition (ext4)
+- /var  partition (ext4)
+- /tmp  partition (ext4)
+- swap  partition [swap]
+
+NOTE: `lsblk` is a very nice tool to doublecheck your partition(s) structure.
+
+First we format to the file systems we want:
+
+```bash
+mkfs.ext2 /dev/sdaxY (/boot)
+mkfs.ext4 /dev/sdaxY (/, /home, /var, /tmp)
+```
+
+Why do I use ext2 for the boot partition? No need to have a journal.
+
+Create /mnt structure, one-liner:
+
+```bash
+mkdir -p /mnt/{boot,home,var,tmp}
+```
+
+And then mount the file systems to /mnt:
+
+```bash
+# Mount / (root)
+mount /dev/sdaxY /mnt
+# Mount /boot, /home, /var, /tmp
+mount /dev/sdaxY /mnt/<point>
+```
+
+Let us not forget to make ("format") our swap and mount it as well:
+
+```bash
+mkswap /dev/sdaxY
+swapon /dev/sdaxY
+```
+
+Installing the actual base system and sudo
+------------------------------------------
+
+Install the base system, with sudo as well.
+
+```bash
+pacstrap /mnt base base-devel sudo
+```
+
+Generate the fstab (so it knows how things are mounted)
+-------------------------------------------------------
+
+This is why we had to mount everything as first, so genfstab
+would know what to do when generating the fstab.
+
+```bash
+genfstab -U -p /mnt >> /mnt/etc/fstab
+```
+
+chroot into the installed system with /bin/bash
+-----------------------------------------------
+
+```bash
+arch-chroot /mnt /bin/bash
+```
+
+Locale (system language)
+------------------------
+
+Depending on what you want, you change the /etc/locale.gen file:
+
+```bash
+nano /etc/locale.gen
+```
+
+NOTE: Use UTF-8 whenever possible.
+
+DOUBLE NOTE: If you are from America, you don't need to change the file.
+
+When done, you simply generate the locales you want and tell the system what you
+want to use.
+
+Generate:
+
+```bash
+locale-gen
+```
+
+Tell the system what we use:
+
+```bash
+echo LANG=en_GB.UTF-8 > /etc/locale.conf
+export LANG=en_GB.UTF-8
+```
+
+Timezone
+--------
+
+Symlink/Set your timezone:
+
+```bash
+ln -s /usr/share/zoneinfo/Europe/Copenhagen /etc/localtime
+```
+
+Set system to the Hardware Clock
+--------------------------------
+
+```bash
+hwclock --systohc --utc
+```
+
+Hostname
+--------
+
+Choose an awesome hostname:
+
+```bash
+echo myhostname > /etc/hostname
+```
+
+Setting up DHCP for my Internet Card
+------------------------------------
+
+systemd setup of your dhcp interface:
+
+```bash
+ip link
+systemctl enable dhcpcd@my-device.service
+```
+
+Just simply using `systemctl enable dhcpcdeth0.service` won't work anymore.
+So I'm getting the correct device with ip link. (Usually the entry under the loop.)
+
+Ramdisk
+-------
+
+Initial ramdisk environment.
+
+```bash
+mkinitcpio -p linux
+```
+
+This actually ran under the pacstrap process, I just like to be safe.
+
+Root Password
+-------------
+
+Be stronk:
+
+```bash
+passwd
+```
+
+Grub (Bootloader)
+-----------------
+
+Well, we need a bootloader:
+
+```bash
+pacman -S grub
+```
+
+If I'm having **Windows** as well on another Partition, I'll also install ***os-prober***.
+
+```bash
+grub-install --target=i386-pc --recheck /dev/sda
+grub-mkconfig -o /boot/grub/grub.cfg
+```
+
+Exit arch-chroot
+----------------
+
+```bash
+exit
+```
+
+Umount /mnt and reboot
+----------------------
+
+Unmount EVERYTHING and reboot the system.
+
+```bash
+umount /dev/sdaxY
+reboot
+```
+
+NOTE: You can use `umount -R /mnt` to recursively unmount everything in /mnt
+
+Login as Root to Arch Linux and permantly set the keymap (keyboard)
+-------------------------------------------------------------------
+
+Now we want to make our keyboard layout permanent:
+
+```bash
+localectl set-keymap --no-convert dk
+```
+
+I obviously have "dk" for Danish layout. Substitute with your own layout.
+
+NOTE: If you are a bloody American, you don't need to do this. US is default.
+
+Check for updates, there's probably none
+----------------------------------------
+
+```bash
+pacman -Syy
+pacman -Syu
+```
+
+Add User and set Password
+-------------------------
+
+```bash
+useradd -m -g users -G lp,scanner,audio,video,optical,network,games,wheel -s /bin/bash username
+passwd username
+```
+
+Change sudoers file using nano
+------------------------------
+
+```bash
+EDITOR=nano visudo
+```
+
+Uncomment wheel group.
+
+`# %wheel ALL=(ALL:ALL) ALL`
+
+Logout of Root
+--------------
+
+```bash
+exit
+```
+
+Login as your username and test sudo with pacman
+------------------------------------------------
+
+```bash
+sudo pacman -Syy
+sudo pacman -Syu
+```
