 ## 🚀 Live Demo — 30-Second Flow
 
-1. **Open the Space** and switch to **Tab 1 — Connect**.
-2. Click **“Connect Gmail”**, grant read-only access, then hit **“Ingest”**.
-3. Jump to **Tab 2 — Analytics** to see tag clouds and sender stats.
-4. Ask questions in **Tab 3 — Ask ReMind** e.g. “Summarise recent Anthropic updates.”
-5. Watch the agents think, then follow the citations back to the original email or bookmark.
+1. **Open the Space** and start with the **"ℹ️ About"** tab to understand the system architecture.
+2. Switch to **"💬 Chat Assistant"** tab to interact with the multi-agent system.
+3. Ask questions like "Search my AI bookmarks" or "Show me my latest emails from news@alphasignal.ai".
+4. Check the **"🏷️ Categories Dashboard"** to see your bookmarks organized by AI categories.  
+5. Watch the agents think in real-time and explore your organized digital knowledge.

 ## 🛠️ Key Components
 
+![ReMind AI System Architecture](data/ai_diagram.png)
+*System architecture showing the multi-agent orchestration and data flow in ReMind*
+
 * **Multi-Agent Orchestrator** — built with *SmolagentS*; assigns Gmail parsing, bookmarking, and RAG tasks to specialists.
-* **LLM Stack** — OpenAI GPT-4o for reasoning, ADA-002 for embeddings (pluggable).
-* **Vector Store** — in-memory FAISS during hackathon (MongoDB Atlas planned).
-* **Gradio 5 UI** — three-tab layout + real-time agent “thoughts” accordion.
+* **LLM Stack** — Qwen3-32B for reasoning and natural language understanding
+* **Vector Store** — in-memory JSON caching for fast bookmark and email access
+* **Gradio 5 UI** — three-tab layout: About, Chat Assistant, and Categories Dashboard with real-time agent "thoughts".
