+# How does it work?
+
+When you open a shulker for the first time, AxShulkers puts a UUID on it:
+
+<img alt="img.png" src="./img.png" width="800"/>
+
+<i>* output from /paper dumpitem</i>
+
+The plugin stores everything in a database, and it finds the items based off the shulker's UUID
+
+<img alt="img_1.png" src="./img_1.png" width="800"/>
+
+<p>So instead of storing the items within the shulker item's nbt, the plugin stores them in a database.
+When a player first opens a shulker, it creates a database entry and after that it will load it into memory as a inventory.
+Because of this the only way to dupe items is to find a dupe in the vanilla minecraft inventories.</p>
+
+<p>However there is a big disadvantage, which is if you copy paste a shulker or duplicate them, they will share the same inventory, which is usually not what people want.
+To prevent shared inventories, you must clear the UUID from shulkers with <b>/axshulkers clear</b> to be able to use them in crates or kits.</p>
