grocy running on mamp pro (web)

[gewoondemax]

Hello thank you for this beautiful 'plugin' for grocy - how ever I do not get it to work. I am a newby in this - running a Mac mini with MampPro and grocy running in web mode.
and must this program run on the same machine as grocy or may that be another on machine?
is there a manual of step by step how to implement the grocy dutch market? thank you. best regards Max
