+## Incident Root-Cause Predictor
+
+### Overview
+The **Incident Root-Cause Predictor** automatically classifies incoming Incidents into categories like *Network, Hardware, Application,* or *Security* based on keywords in the description.  
+This helps in faster triaging and routing tickets to the right support teams.
+
+---
+
+## How It Works
+1. A user submits an Incident.
+2. A **Business Rule** runs on insert.
+3. It calls the **Script Include – `RootCausePredictor`**.
+4. The predictor scans the description and returns a probable root-cause category.
+
+---
+## Business Rule Script (How to call Script Include on BR)
+    var util = new global.RootCausePredictor();
+    
+(function executeRule(current) {
+    var util = new global.RootCausePredictor();
+    var cat = util.predict(current.description);
+    current.u_root_cause = cat;
+    current.work_notes = "Auto-classified as: " + cat.toUpperCase();
+})(current);
+
+--------------
+## Sample Input and Output
+Input : A user logs a ticket:
+“Wi-Fi keeps disconnecting every few minutes.”
+
+The Script Include scans for the word “Wi-Fi”, which matches the Network keyword list.
+OutPut: 
+
+System automatically sets field u_root_cause = "Network"
+Work note added: “Auto-classified as: NETWORK”
