Installation
The easiest way for now is to use the Flash Tool from official flashing guide, replacing linux.img in the firmware package with planet-geminipda.img and linux_boot.img with boot.img-planet-geminipda. In the Android 7.1 downloads it appears the linux_boot.img is distro_boot.img. If you want it to reflect just generic linux_boot.img you also need to update the Scatter file.
Alternative installation
The device package also includes an initramfs hook, which will try to mount the userdata and linux partitions, looking for a /postmarketOS.img file (pmbootstrap exports as planet-geminipda.img so you'd need to rename). This can be used for non-intrusive installation inside of the Android user space and only requires a small linux partition and boot image.
That Image file needs to be expanded to the wanted size in advance, for example:
% truncate -s 2G postmarketOS.img
