+## How to set the keyboard to a English-US layout
+Go to Localization options, then:
+
+Locale -> remove en_GB, add en_US.UTF-8, then choose enUS.UTF-8 as default
+
+Keyboard layout -> choose a generic keyboard -> in the next list you'll see only UK keyboards. Go down and choose "other" -> Choose English (US) -> Choose English (US) agian

+## Notes on how to create an image and copying it on multiple hubs
+Ingeneral, follow the instructions on how to setup a regular hub, except:
+* Do not expand the file system. It seems that HypriotOS and Jessie both expand it automatically. So in order to turn it off, edit /boot/boot/cmdline.txt and remove the call to init=/usr/lib/raspi-config/init_resize.sh
+* Istead, use fdisk to extend it to a smaller partition. You can find more infomration here - http://www.raspberry-projects.com/pi/pi-operating-systems/raspbian/troubleshooting/expand-filesystem-issues . In general:
+  * sudo fdisk /dev/mmcblk0
+  * Then press 'p' to see the current partitions on the disk
+  * Now delete the 2nd partition (it won't actually delete the data on it)
+  * Press 'd' > Enter
+  * Press '2' > Enter
+  * Now re-create it:
+  * Press 'n' > Enter
+  * Press 'p' > Enter
+  * Press '2' > Enter
+  * Enter the First sector and the same value as the original /dev/mmcblk0p2 partition
+  * Set the new size. I used +3G to create a 3GB partition (you'll need some space for building the hub images)
+  * Now press 'p' > Enter to see the new partition setup.
+  * Finally press 'w' > Enter to write it
+  * Now reboot: sudo shutdown -r now
+  * Once its back do the resize: sudo resize2fs /dev/mmcblk0p2
+* Use docker-machine to install docker dependencies, etc
+* Then run update & upgrade
+
+Then save the image
+* See this post for information - https://raspberrypi.stackexchange.com/questions/8305/how-to-make-an-image-img-from-whats-on-the-sd-card-but-as-compact-as-the-or 
+* make sure partitions are unmounted
+* sudo fdisk -l /dev/mmcblk0
+* sudo dd if=/dev/mmcblk0 of=openbadge-hub-py.img bs=512 count=<END of second partition + 1>
+
+Burn image into a new SD card
+* Use dd, flash or Etcher.io
+
+After you create a copy, make sure to:
+* Change the hostname
+* Extend the filesystem
