-# ServiceNow Script: Submit Catalog Item via Scheduled Job
+# Submit catalog item (Scheduled Job)
 
-This script demonstrates how to programmatically submit a ServiceNow **catalog item** using the `Cart` API. It is designed to be run as a **Background Script** or adapted into a **Scheduled Job**. The script includes error handling and logging, and can be extended to support additional use cases such as variable injection or duplicate request prevention.
+This snippet demonstrates how to submit a Service Catalog item programmatically from server-side code using the `sn_sc.CartJS` API.
 
-## 📜 Overview
+## Purpose
+
+Add an item to the Service Catalog cart with variables and perform checkout to create the request/req item records.
+
+## Script behavior
+
+- Creates a `sn_sc.CartJS()` cart instance.
+- Calls `addToCart()` with `sysparm_id`, optional `sysparm_quantity`, optional `sysparm_requested_for`, and a `variables` object.
+- Calls `checkoutCart()` to place the order.
+- Logs success or error information using `gs.info`, `gs.warn`, and `gs.error`.
+
+## Placeholders to replace
+
+- `SYS_ID_OF_CAT_ITEM`: the `sys_id` of the Catalog Item (`sc_cat_item` record).
+- `SYS_ID_OF_REQUESTED_FOR_USER`: (optional) the `sys_id` of the user to set as Requested For. Remove the property to default to the current user.
+- `variable_name1`, `variable_name2`, `variable_nameN` :variable names expected by the catalog item. Use the variable name (not label) unless your instance expects variable IDs.
+
+## Expected returns
+
+You will receive an object containing the request number representating of the created `sc_request` with a `sc_req_item` Item. If unsure, log `JSON.stringify(checkoutInfo)` to inspect.
