+# Automatic Dashboard Refresh Script for ServiceNow
+
+This script, designed for ServiceNow, automatically refreshes a specified dashboard daily at 12:00 AM. By creating a Scheduled Job with this script, users can ensure their dashboard data is updated without manual intervention.
+
+## Overview
+
+ServiceNow’s Scheduled Jobs feature allows you to run server-side scripts at specified intervals. This script uses the `pa_dashboards` table to update the `last_refreshed` field on a given dashboard record, simulating a refresh.
+
+## Prerequisites
+
+- Access to ServiceNow with permissions to create and run Scheduled Jobs.
+- The `sys_id` of the dashboard you want to refresh.
+
+## Setup Instructions
+
+1. **Navigate to Scheduled Jobs**:
+   - Go to **System Definition > Scheduled Jobs** in ServiceNow.
+
+2. **Create a New Scheduled Job**:
+   - Set the job to run at **12:00 AM** daily.
+
+3. **Add the Script**:
+   - Copy and paste the script below into the Scheduled Job’s script field.
+   - Replace `YOUR_DASHBOARD_SYS_ID` with the `sys_id` of the dashboard you want to refresh.
+
+4. **Save and Activate the Job**:
+   - Ensure the job is active and will repeat daily.
