UMCG or RUG computer
If you work on an UMCG computer (or via UMCG Anywhere) you need to use a special shortcut: "Mendeley in Word" to use Mendeley to cite in your papers. Within "Mendeley in Word" you can find it under References (in Dutch: Verwijzingen).
When working from a RUG computer, the Mendeley plugin is already installed by default.
Laptop or PC at home
To install the Mendeley Plugin you need to first close Word and then on Mendeley Desktop go to Tools > Install MS Word Plugin.
