 ### Sophisticated Storage
 
-Barrels and Chests: 
+**Barrels and Chests**: Make sure you're using Sophisticated Storage barrels and/or chests when doing all this. Not sure if it matters, but I think it does. You can filter in item lookups on a mod-by-mod basis by typing `@mod` beforehand. So when I look up barrels from Sophisticated Storage I can search `@soph barrel`.
 
 **Storage Controller**: This is a block which serves as your "connection point" to all your different inventories. I think how the mod handles multiple inventories is to take multiple, separate chests and "merge them together" into one "combined" chest. This is that chest. Works with Storage Links.
