+
+# 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.
+
+# Installation with sshramdisk image
+ - You may use the  rpi_inst.img.gz file created by an evbarm build.
+ - Connect Ethernet Cable to RPI.
+ - After starting DHCP client,SSH login to RPI with user "sysinst",passwd "netbsd".
+ - sysinst started! 
+
+# Updating the firmware
+ - [rpi firmware files](https://github.com/raspberrypi/firmware/tree/master/boot)
+   - Copy all files except 'kernel*img' into /boot and reboot
+
+# Additional links
+ - [ARM userland utilities](https://github.com/jaredmcneill/userland)
+
 # What works
- - multi-user boot with root on SD card and serial console
+ - multi-user boot with root on SD card
+ - serial or graphics console (with EDID query / parsing)
+ - X windows.
+ - USB (host); control, interrupt and bulk transfers. Has some stability issues that are being worked on. man page missing.
+ - USB Ethernet
+ - RNG: works
+ - I²C: works, could use enhancements, man page
+ - SPI: works, could use enhancements, man page
+ - VCHIQ: work in progress. man page missing. (-current)
+ - Audio: works. man page missing. (-current)
 
 # What needs work
- - USB (host): work in progress
- - I²C: work in progress
- - SPI: work in progress
+ - USB (host); isochronous transfers. DMA support.
+ - DMA controller driver / dmover(9) backend
+ - Teach sdhc(4) about dmover; not Raspberry Pi specific
+ - hardfloat; not Raspberry Pi specific
+ - earm ABI; not Raspberry Pi specific
  - GPIO
- - framebuffer
- - almost everything relating to working with the VideoCore IV
