 ### Updating physical items
 Once the item updater is enabled for a specific item, every physical instance of that item is considered _outdated_ and will be updated. An outdated item can only be updated **once** (performance save) when enabling the item updater, unless you apply further changes to the item. Every change you apply in the item edition GUI will make physical item instances _outdated_ again till they are updated.

+### (Not recommended) Enabling the updater for every item
+If you do not want to worry about players having outdated items here and there on your server, you might want to enable the item updater for every item in the plugin. **This is possible however not recommended.**\
+The item updater was designed to hot-nerf items in players' inventories once they have been generated. It is not designed to mass-update every item on your server. The more items you have, the higher the performance the plugin will need in order to keep them updated.\
+The item updater is **100% useless** for items which have not been changed after being generated. In order to save performance, MI first checks if a physical item has some non-applied item change, and then updates the item if it is considered outdated. Enabling the item updater for 100% of your items generates useless update checks.
+
+You can manually enable the item updater for every item in your server using the following command: `/mi update apply 2 2`. This loops through every item in your config files and registers them in the item updater list.
