 ## 🚀 Overview
 
-This is a sub-project of **LFDT Labs AIFAQ Prototype (Studio Branch)**. The main goal is to build an AI agent that interacts with the communities to get feedback from potential users.
+The **Hyperledger Labs AIFAQ Prototype (Agents Branch)** is an open-source conversational AI tool that simplifies knowledge discovery within vast document repositories. Our mission: to **support users, developers, and communities by providing an intuitive conversational interface** that answers questions about specific contexts—no more wading through oceans of documents!

+## 🧩 Features
+
+- Conversational AI for targeted question answering
+- Supports RAG (Retrieval Augmented Generation) for enhanced accuracy
+- Easy integration via API and UI samples
+- Extensible architecture for multi-agent support

+## 🛠️ Architecture
+
+<img src="./images/architecture.png" alt="LLM chatbot architecture" width="750"/>
+
+**Workflows:**
+
+1. **Data Ingestion:** Load context documents → create vector DB (e.g., from ReadTheDocs or GitHub issues/PRs)
+2. **Chat Workflow:** Accept user queries → retrieve context → generate answer
+
+Currently uses [Mistral Models](https://mistral.ai) (e.g., Mixtral-8x7B-v0.1). Plans to evaluate other open-source models in the future.
+

+
+## 📝 Setup (Agents Branch)
+
+```bash
+git clone https://github.com/hyperledger-labs/aifaq.git
+cd aifaq
+git checkout agents
+python -m venv venv
+source venv/bin/activate
+cd src/mvt
+pip install -r requirements.txt
+python create_directories.py
+```
+
+### Environment Variables
+
+Edit your `.env` file:
+
+```env
+MISTRALAI_API_KEY=<required - get from https://auth.mistral.ai/ui/login>
+OPENAI_API_KEY=<optional>
+HF_TOKEN=<required - get from https://huggingface.co/settings/tokens>
+```

+
+👉 Visit [Mixtral-8x7B-v0.1 on HuggingFace](https://huggingface.co/mistralai/Mixtral-8x7B-v0.1) and request access.

+
+### Launch
+
+The application supports two modes of operation:
+
+#### Production Mode (Default)
+```bash
+streamlit run app.py
+```
+
+**Note:** Production mode requires authentication credentials to be configured in `.streamlit/secrets.toml`. If credentials are not configured, the application will show an error message with options to either:
+- Switch to development mode
+- Configure the required credentials
+
+#### Development Mode
+```bash
+streamlit run app.py dev
+```
+
+**Note:** Development mode provides full functionality without authentication requirements, making it ideal for testing and development.
+
+### Authentication Configuration (Production Mode)
+
+For production mode, you need to configure authentication credentials in `.streamlit/secrets.toml`:
+
+```toml
+# For Auth0 authentication
+[auth.auth0]
+domain = "your-domain.auth0.com"
+client_id = "your-client-id"
+client_secret = "your-client-secret"
+server_metadata_url = "https://your-domain.auth0.com/.well-known/openid_configuration"
+client_kwargs = { "prompt" = "login"}
+
+# OR for Google OAuth
+[auth.google]
+client_id = "your-google-client-id"
+client_secret = "your-google-client-secret"
+server_metadata_url = "https://accounts.google.com/.well-known/openid_configuration"
+
+# General auth settings
+[auth]
+redirect_uri = "your-redirect-uri"
+cookie_secret = "your-cookie-secret"
+```
