+Create virtual disk of pan.do/ra
+
+== ubuntu-vm-builder setup ==
+
+due to https://bugs.launchpad.net/ubuntu/+source/vm-builder/+bug/676132
+we need to use maverick-proposed repository:
+
+ echo "deb http://archive.ubuntu.com/ubuntu/ maverick-proposed restricted main multiverse universe" > /etc/apt/sources.list.d/ubunt-proposed.list
+ apt-get update
+ apt-get -t maverick-proposed install ubuntu-vm-builder
+
+
+due to https://bugs.launchpad.net/vmbuilder/+bug/683614
+building vbox images does not work. install virtualbox_vm.py:
+    sudo cp virtualbox_vm.py /usr/lib/python2.6/dist-packages/VMBuilder/plugins/virtualbox/vm.py
+
+(or change vbox to kvm to build kvm image)
+
+with that installed build image:
+
+ ./build.sh
+
+this will create a vdi image in pandora/
+
+== VirtualBox Usage ==
+Now you can create a new VirtualBox machine, use vdi image as existing hard disk.
+Before starting up you have to adjust some settings:
+ In System -> Processor enable PAE/NX
+ In Storage remove disk from SATA Controller
+            add disk to IDE Controler and enable "Use host I/O cache"
+    
+ In Network -> Adpater 1 set to Bridged Adapter with your connected controller
+
+== Use for development ==
+Login via ssh or in terminal as pandora with password pandora
+
+Adjust your bzr configuration with bzr whoami:
+ bzr whoami "Pando the Panda <pan.do@pan.do>"
+
+Pan.do/ra is installed in /srv/pandora and is served with nginx on http://pandora.local
+
+
+== Update ==
+to get the latest version of pan.do/ra
+ cd /srv/pandora
+ bzr pull
+ cd static/oxjs
+ bzr pull
+
+you might have to adjust the database at this point. now restart pandora daemons
+
+ service pandora restart
+ service pandora-tasks restart
+ service pandora-encoding restart
