 ## Adding new casing types
 See [MACHINE_MODELS.md](MACHINE_MODELS.md) for an explanation of machine models and what casings are.
-You can add new casings using the `register` function in the `MIMachineEvents.registerCasings` event.
+You can add new casings using the `MIMachineEvents.registerCasings` event.
+- Use the `register` function if you will also be adding a JSON model for the casing.
+- Use the `registerBlockImitation` function to add a casing that will imitate another block.
 
-Remember that the top, side and bottom textures of a casing must be `modern_industrialization:textures/block/casings/<casing name>/{top,side,bottom}.png`.
