+An overview of the files on the /boot/firmware partition (the 1st partition
+on the SD card) used by the Ubuntu boot process (roughly in order) is as
+follows:
+
+* bootcode.bin   - this is the second stage bootloader loaded by all pis with
+                   the exception of the pi4 (where this is replaced by flash
+                   memory)
+* config.txt     - the first configuration file read by the boot process
+* syscfg.txt     - the file in which system modified configuration will be
+                   placed, included by config.txt
+* usercfg.txt    - the file in which user modified configuration should be
+                   placed, included by config.txt
+* start*.elf     - the third stage bootloader, which handles device-tree
+                   modification and which loads...
+* uboot*.bin     - various u-boot binaries for different pi platforms; these
+                   are launched as the "kernel" by config.txt
+* boot.scr       - the boot script executed by uboot*.bin which in turn
+                   loads...
+* vmlinuz        - the Linux kernel, executed by boot.scr
+* initrd.img     - the initramfs, executed by boot.scr
+* meta-data      - meta-data for cloud-init; usually just contains the
+                   instance id
+* network-config - network configuration for cloud-init; edit this to set up
+                   wifi access points and other networking settings
+* user-data      - user-data for cloud-init; edit this to configure initial
+                   users, SSH keys, packages, etc.
