+# Installation
+ - You may use the rpi.img file created by an arm build.
+   - An example can be found in the '/evbarm/binary/gzimg/' directory under releng.netbsd.org
+   - 'obj/releasedir/evbarm/binary/gzimg/' if you run (for example) './build.sh -m evbarm -u release'
+     - <i>gunzip and dd</i> this img to your sd card.
+
+	   dd if=rpi.img of=/dev/disk1
+
+ - Using a serial console
+   - By default the rpi.img is set to use the HDMI output; to change mount rpi.img (it's a FAT filesystem)
+
+	   edit cmdline.txt and remove '"console=fb"'
+   - proceed with the 'dd'
+
+ - Growing the root file-system
+   - Copy /boot/cmdline.txt to /boot/cmdline.txt.orig
+   - Edit /boot/cmdline.txt and add the '-s' flag to the end of the first line of text to boot into single-user mode.
+   - Reboot, and at the prompt to enter the passname of shell, press
+	   return for the default (/bin/sh).
+   - At the # prompt, type
+
+        "disklabel -i ld0" and press return.
+   - At the partition> prompt type "A" and press return.
+
+           Adjust disklabel sector from 4194304 to 62333952 [n]?
+           Type "y" and press return.
+   - partition> prompt type "a" and press return.
+
+           Filesystem type prompt, press return to use the current value (4.2BSD).
+           Start offset prompt, press return to use the current value.
+           Partition size prompt, type "$" and press return to grow the
+           partition to use all available free space.
+   - partition> prompt type "W" to save the changes to the disklabel.
+
+           Confirm this choice by typing "y" at the Label disk prompt.
+           Type "Q" and press return to quit disklabel.
+   - At the # prompt (shell), type
+
+           fsck -fy /dev/rld0a
+           resize_ffs -y /dev/rld0a
+   - This may take a few minutes, be patient!
+
+           fsck -fy /dev/rld0a
+           mount /dev/ld0e /boot
+           mv /boot/cmdline.txt.orig /boot/cmdline.txt
+           reboot
+    - When the system comes back up, the root file-system will have been expanded to
+	   fill the SD card.

+# Updating the firmware
+ - [rpi firmware files](https://github.com/raspberrypi/firmware/tree/master/boot)
+   - Copy all files except 'kernel*img' into /boot and reboot
