+## Rule Changes
+
+```cjson
+{
+    // note you must disable the base rule as it can report incorrect errors
+    "no-useless-constructor": "off",
+    "@typescript-eslint/no-useless-constructor": "error",
+}
+```
+
 ## When Not To Use It
 
 If you don't want to be notified about unnecessary constructors, you can safely disable this rule.
