-Your item definitions go here.
+Naming conventions
-All items files have to have the ".items" file extension and must follow a special syntax.
+------------------
 
-Check out the openHAB documentation for more details:
+In `uncritical.items` you'll find all the items that will not trigger any rules
-https://www.openhab.org/docs/configuration/items.html
+if you update the file. In `critical.<object>.items` you will find items that
+will probably trigger rules when you update the file.
+
+The separation was made so that uncritical items can be safely modified without
+triggering any rules.
