 #### Scripts
 
-##### New: isStringInList
+##### New: IsStringInList
 
-# Release Notes: `isStringInList`
-## Description
-Checks whether a specified string exists within a named list in Cortex XSOAR. Returns `"yes"` if found, `"no"` otherwise. Supports optional wildcard and case-insensitive matching.
-## Use Cases
-- Validate if a user, domain, or indicator is part of a predefined list.
-- Control playbook flow based on list membership.
-- Support allow/block decisions using list-based logic.
-- Match values using wildcards or case-insensitive comparison.
-## Inputs
-- `searchString` (string): The value to search for.
-- `listName` (string): The name of the list to search in.
-- `caseInsensitive` (string, optional): Set to `"true"` to ignore case when matching. Default is `"false"`.
-- `useWildcard` (string, optional): Set to `"true"` to enable `*` and `?` wildcard matching. Default is `"false"`.
-## Outputs
-- `"yes"` if the string is found in the list.
-- `"no"` if the string is not found or the list is empty.
-## Limitations
-- Wildcard matching uses basic patterns: `*` for any sequence, `?` for a single character.
-- Case-insensitive and wildcard logic do not support partial substring matching.
-inputArray: the context array/list data
-listName: the XSOAR system list.
