+### Separate boot (ext4) and root (f2fs) partitions
+
+Replace sdX in the following instructions with the device name for the SD card as it appears on your computer.
+
+1. Zero the beginning of the SD card:
+   ```
+   dd if=/dev/zero of=/dev/sdX bs=1M count=8
+   ```
+1. Start fdisk to partition the SD card:
+   ```
+   fdisk /dev/sdX
+   ```
+1. At the fdisk prompt, create the new partition:
+   - Type **o**. This will clear out any partitions on the drive.
+   - Type **p** to list partitions. There should be no partitions left.
+   - Type **n**, then **p** for primary, **1** for the first partition on the drive, **4096** for the first sector,
+     and then type **+256M** for the last sector.
+   - Type **n**, then **p** for primary, **2** for the second partition on the drive, and then press *ENTER* twice to accept the default first and last sector.
+   - Write the partition table and exit by typing **w**.
+1. Create the boot filesystem:
+   ```
+   mkfs.ext4 /dev/sdX1
+   ```
+1. Mount the filesystem:
+   ```
+   mkdir boot
+   mount /dev/sdX1 boot
+   ```
+1. Create the root filesystem:
+   ```
+   mkfs.f2fs /dev/sdX2
+   ```
+1. Mount the filesystem:
+   ```
+   mkdir root
+   mount /dev/sdX2 root
+   ```
+1. Download and extract the root filesystem:
+   ```
+   wget http://os.archlinuxarm.org/os/ArchLinuxARM-aarch64-latest.tar.gz
+   bsdtar -xpf ArchLinuxARM-aarch64-latest.tar.gz -C root
+   ```
+1. Move boot files to the first partition
+   ```
+   mv root/boot/* boot
+   ```
+1. Download appropriate U-Boot package from [releases](//github.com/RoEdAl/alarm-uboot-sunxi-aarch64/releases):
+   ```
+   wget https://github.com/RoEdAl/alarm-uboot-sunxi-aarch64/releases/download/vyyy.mm-r/uboot-<your board name>-yyyy.mm-r-aarch64.pkg.tar.xz
+   ```
+1. Extract required U-Boot binary and compiled script from package:
+   ```
+   bsdtar -xf uboot-<your board name>-yyyy.mm-r-aarch64.pkg.tar.xz boot/u-boot-sunxi-with-spl.bin boot/boot.scr
+   ```
+1. Install the U-Boot bootloader:
+   ```
+   dd if=boot/u-boot-sunxi-with-spl.bin of=/dev/sdX bs=8k seek=1
+   sync
+   rm boot/u-boot-sunxi-with-spl.bin
+   ```
+1. Download appropriate DTBS package from [releases](//github.com/RoEdAl/alarm-uboot-sunxi-aarch64/releases) (*OrangePi Zero Plus* only):
+   ```
+   wget https://github.com/RoEdAl/alarm-uboot-sunxi-aarch64/releases/download/vx-y/orangepi-dtbs-x.yy-r-aarch64.pkg.tar.xz
+   ```
+1. Extract and install DTB (*OrangePi Zero Plus* only):
+   ```
+   bsdtar -xf orangepi-dtbs-x.yy-r-aarch64.pkg.tar.xz boot/dtbs-extra/allwinner/sun50i-h5-orangepi-zero-plus.dtb
+   sync
+   ```
+1. Inform bootloader that root filestystem is on second partition:
+   ```
+   touch boot/root-is-on-2nd-partition
+   ```
+1. Add `fstab` entry to mount boot partition:
+   ```
+   echo '/dev/mmcblk0p1 /boot ext4 defaults 0 2' >> root/etc/fstab
+   ```
+1. Optionally configure *systemd-journald* service to store log data only in memory:
+   ```
+   mkdir -p root//usr/lib/systemd/journald.conf.d
+   echo '[Journal]' > root//usr/lib/systemd/journald.conf.d/storage-volatile.conf
+   echo 'Storage=volatile' >> root//usr/lib/systemd/journald.conf.d/storage-volatile.conf
+   ```
+1. Umount the partitions:
+   ```
+   umount root boot  
+   ```
+1. Insert the micro SD card into the board, connect ethernet, and apply 5V power.
+1. Use the serial console or SSH to the IP address given to the board by your router.
+   - Login as the default user *alarm* with the password *alarm*.
+   - The default *root* password is *root*.
+1. After logging into the system install U-Boot and DTBS packages:
+   ```
+   pacman -U https://github.com/RoEdAl/alarm-uboot-sunxi-aarch64/releases/download/vx-y/uboot-<your board name>-yyyy.mm-r-aarch64.pkg.tar.xz https://github.com/RoEdAl/alarm-uboot-sunxi-aarch64/releases/download/vx-y/<brand-name>-dtbs-x.yy-r-aarch64.pkg.tar.xz
+   ```
+1. Install `f2fs-tools` package and rebuild *initcpio*:
    ```
+   pacman -Syu f2fs-tools
+   mkinitcpio -p linux-aarch64
+   ```
+
 ## Build issues
 
 * `uboot-*` packages: Due to `git-apply` behaviour packages you must build `uboot-*` packages  **outside** a git repository.
