Database "Category Article": how to follow the whole database?

[xtech]

Hi,

one of my databases has categories, and the first page has a "Category Articles" style template.

I would like to put a follow button on the top of the template, like this, to follow the whole database (all categories):

<div class='ipsPos_right ipsResponsive_noFloat ipsResponsive_hidePhone'>
	{template="follow" app="core" group="global" params="'cms','categories' . $category->database_id, $category->_id, \IPS\cms\Records::containerFollowerCount( $category )"}
</div>

The problem is that i do not know the correct parameters to provide the "follow" template. Anyone knows where is the dev documentation for this or how can i put this working?
