Follow these steps if you want to run Sabily on top of another operating system

Virtual Box is a virtualization software, that means you can execute a "guest" operating system on top of a "host" operating system. For example, if you have Windows installed on your computer, you can run Sabily like an application on Windows. No need to burn a DVD with Sabily, then to install it on your computer... So if you are afraid to lose data by installing Sabily on your computer, or if you just want to quickly test it, install Virtual Box, download the Sabily image and execute it!

Here are the detailed instructions:

• Download and install VirtualBox here
• Download the Sabily image here (download both files, .vmdk and .ovf)
• Launch virtualBox and select "import virtual appliance", then browse to the .ovf file you downloaded (the .ovf file and .vmdk must be in the same folder)
• Review the machine settings (especially memory, it is set to 512MB, but you can increase it if you have more memory) and launch it.
• Log in using:  username -> test, password -> S)bilY  (the keyboard is set to qwerty by default)
