+#### Note on JSON values types
+When checking the value of json keys, you have to consider the type of the value. 
+  - mig-t will convert each int or float type as string, this means that when using the check operators, you should always use a string, not an int or a double.
+  - checking a value that is a JSON Array is only allowed when using the `contains` or `not contains` or `is subset of` operators
+  - When matching a JSON Array, the values of the array are all converted to string

 ### Note for the active tests
 
 If you need to do a check on an active test, you have to do a `validate` operation, which is basically an operation where you can do checks
