+# Instructions for creating a PureOS Image for PinePhone by mozzwald
+########################################################################
+# You will need u-boot-tools package for your distro and it helps
+# to have binfmt and qemu packages for chrooting to the image.
+# Paths and devices may be different on your system. Always verify
+# before blindly copying and pasting commands.
+
+# Make a new working directory
+mkdir ~/purepp
+cd ~/purepp
+
+# Download and extract PinePhone phosh image (check for newer releases if you like)
+wget https://images.postmarketos.org/pinephone/pine-pinephone-20200218-phosh.img.xz
+unxz -d pine-pinephone-20200218-phosh.img.xz

+# Download and extract PureOS Librem 5 image (check for newer releases if you like)
+wget http://downloads.pureos.net/amber/phone/gnome/librem5/2020-02-25/librem5.img.xz
+unxz -d librem5.img.xz

+# Make temporary dirs for mounting images
+mkdir pmos-boot pmos-root pureos-boot pureos-root
+
+# List used loop devices
+losetup -a
+# List all loop devices
+ls /dev/loop*
+
+# The remaining commands should be run with sudo or as root user (sudo su)
+
+# Pick an unused loop device (5 in my case) and mount pmOS image with partitions
+losetup -P /dev/loop5 pine-pinephone-20200218-phosh.img

+# Pick an unused loop device (6 in my case) and mount PureOS image with partitions
