For anybody who may be using Codio.com for on-line development and or testing stuff out I have an install script that will set Silverstripe up on Codio box.

Ironically I have stopped using Codio now, it all worked as of last week though.
Follow the instructions and you will quickly get to the the Silverstripe install screen with very little effort.
Note: you will need a full Codio account so probably not much use unless you are already using it.
