+# API information (WIP)
+This API information is WIP. The mod API is still pretty much unofficial;
+this mod is mostly seen as standalone for now.
+This may change in the future development of MineClone 2. Hopefully.
+
+## Groups
+Items in group `food=3` will make a drinking sound and no particles.
+Items in group `food` with any other rating will make an eating sound and particles,
+based on the inventory image or wield image (whatever is available first).
+
+## Suppressing food particles
+Normally, all food items considered food (not drinks) make food particles.
+You can suppress the food particles by adding the field
+`_food_particles=false` to the item definition.
