Hi,
That is still relavent to an extent, most of the configuration does apply to SharePoint 2013. SharePoint 2013 does have new features which are noted in the XML file.
To make it easier, there is an AutoSPInstallerGUI tool which has been developed. This can be found here: https://autospinstallergui.codeplex.com/
There is also the AutoSPSourceBuilder to download and organise all your pre-reqs. This can be found here: https://autospsourcebuilder.codeplex.com/
