+        📋 **How it works:**
+        1. The app fetches your name, project name, and Hackathon track details. You can update this information. **Please ensure the details are accurate before proceeding to generate the certificate.**
+        2. Click "Generate Certificate" to create your personalized certificate. You can't make multiple entries; regenerating gives a new image but doesn't replace it in the dataset. The dataset is mainly for records, so no need to worry if you have entered incorrect info initially.
+        2. Download the certificate image file
+        3. Click "Add to LinkedIn Profile" - this opens LinkedIn with pre-filled details:
+           - ✅ Certificate name: "Gradio Agents & MCP Hackathon 2025"
+           - ✅ Organization: "Hugging Face"
+           - ✅ Issue date: June 2025
+           - ✅ Certificate ID
+        4. **Upload your certificate image** in the "Certification media" field
+        5. **Add skills**: MCP, AI Agents, Gradio, Hugging Face
+        6. Click "Add" to save to your LinkedIn profile!
+        💡 **Note**: LinkedIn doesn't allow automatic image uploads for security reasons, so you'll need to manually upload your certificate image.
