+# 📅 Day 5 — Automation, Error Handling, and Final Polish
+
+## 🎯 Goal
+Convert the manual workflow into a **fully automated, production-ready system**.
+
+---
+
+## 🧩 Tasks
+
+### 1. Schedule for Automation
+- Replace the Manual Trigger with a **Cron Node**.
+- Example schedule: Run daily at 3 AM.
+0 3 * * *
+
+yaml
+Copy code
+
+---
+
+### 2. Implement Error Handling
+- Create a separate **Error Workflow**.
+- Add a **Start on Error** trigger.
+- Connect it to a **Slack/Email Node**:
+The Daily Sales Analysis workflow failed. Please check the logs.
+
+yaml
+Copy code
+
+---
+
+### 3. Clean Up and Document
+- Rename all nodes descriptively:
+- `Fetch Shopify Orders`
+- `Analyze Sentiment in Python`
+- `Send Daily Slack Report`
+- Add **comments** inside your Python code.
+- Use **Sticky Notes** in n8n to explain logic visually.
+
+---
+
+### 4. Final Test
+- Deactivate → Review → Activate.
+- Monitor the first scheduled run end-to-end.
+- Validate data accuracy and notification triggers.
+
+---
+
+## ✅ Deliverable
+A **fully automated**, **scheduled**, and **monitored** workflow that:
+- Runs daily at a fixed time.
+- Generates and distributes reports.
+- Sends alerts for anomalies.
+- Notifies the team on failure.
