+# Extract User Roles from JSON
+
+---
+
+## Overview
+This ServiceNow background script takes a JSON of usernames and their titles (roles) and groups all roles under each **unique user**.  
+It prints the result in the **System Logs** in ServiceNow. This helps admins quickly see **unique users and all their roles**, avoiding duplicates.
+
+---
+
+## Use Case
+For example, if a user appears multiple times with different roles:
+
+- `tammie.schwartzwalde` appears as both:
+  - Senior Auditor
+  - Payroll Generalist  
+
+The script will show **all roles together** for that user, without repeating duplicates.

+
+## Logic Flow
+1. Define the JSON array of user details.  
+2. Create an object to hold **unique users** and their roles.  
+3. Loop through each JSON entry:
+   - Trim and validate the title.
+   - Add it to the user's array if it doesn’t already exist.  
+4. Log each user and their unique roles.  
+5. Display the total number of unique users.
