This documentation is not using the current rendering mechanism and is probably outdated. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.
yag depends on two other extensions which you have to install first:
- pt_extbase – a collection of libraries used throughout this extension.
- pt_extlist – a list generator used to render all kinds of lists, pagers and filters.
In order to install YAG, you have to set up those two extensions in the order given above (pt_extbase, pt_extlist). After that, the installation of YAG is quite straight-forward.
