+# Ada AI Coding Environment
+
+A specialized AI coding assistant that helps with code analysis, debugging, and generation.
+
+## Features
+
+- 🤖 **AI-Powered Code Assistant**: Uses Gemini 2.5 Flash Preview for intelligent code analysis
+- 💬 **Real-time Chat**: Stream responses with markdown rendering
+- 📝 **Code Editor**: Built-in CodeMirror editor with syntax highlighting
+- 🔐 **Secure Authentication**: Firebase Auth with Google OAuth and Email/Password
+- 💾 **Chat History**: Persistent storage in Firestore
+- 🚀 **Code Compilation**: Direct integration with online compiler
+- 📱 **Mobile Responsive**: Works seamlessly on desktop and mobile
+
+## Tech Stack
+
+**Frontend:**
+- Vanilla JavaScript (ES6+)
+- Tailwind CSS
+- CodeMirror (code editor)
+- LZString (compression)
+- Firebase SDK (Auth & Firestore)
+- Marked.js (markdown rendering)
+
+**Backend:**
+- Python 3.x
+- Flask
+- Google Generative AI SDK (Gemini 2.5 Flash Preview)
+- Firebase Admin SDK
+- Flask-CORS
+
+**Database:**
+- Firebase Firestore (NoSQL)
+
+## Setup
+
+### Prerequisites
+- Python 3.8+
+- Node.js (for frontend development)
+- Firebase account
+- Google AI API key
+
+### Backend Setup
+
+1. Clone the repository:
+```bash
+git clone https://github.com/notamitgamer/ada-web.git
+cd ada-web
+```
+
+2. Install Python dependencies:
+```bash
+pip install -r requirements.txt
+```
+
+3. Create a `.env` file (use `.env.example` as template):
+```bash
+cp .env.example .env
+```
+
+4. Configure environment variables in `.env`:
+```
+GEMINI_API_KEY=your_actual_gemini_api_key
+FIREBASE_CREDENTIALS={"type":"service_account",...}
+PORT=5000
+```
+
+5. Run the backend:
+```bash
+python backend.py
+```
+
+### Frontend Setup
+
+The frontend is a static HTML application. Simply open `index.html` in a browser or serve it using a local server:
+
+```bash
+python -m http.server 5500
+```
+
+Then visit: `http://localhost:5500`
+
+## Firebase Configuration
+
+### Firestore Database Schema
+
+```
+users (collection)
+ ├─ {uid} (document)
+ ├─ email: string
+ ├─ displayName: string
+ ├─ photoURL: string
+ ├─ createdAt: timestamp
+ └─ chats (subcollection)
+ └─ {chatUUID} (document)
+ ├─ title: string
+ ├─ createdAt: timestamp
+ ├─ updatedAt: timestamp
+ └─ messages: array[
+ {
+ role: "user" | "model",
+ content: string,
+ timestamp: timestamp
+ }
+ ]
+```
+
+### Firebase Service Account
+
+1. Go to [Firebase Console](https://console.firebase.google.com/)
+2. Select project: `ada-ai-aranag`
+3. Navigate to Project Settings > Service Accounts
+4. Generate new private key
+5. Use the downloaded JSON for `FIREBASE_CREDENTIALS` environment variable
+
+## API Endpoints
+
+### POST `/api/chat`
+Streams AI responses for code queries.
+
+**Headers:**
+```
+Authorization: Bearer <firebase_id_token>
+Content-Type: application/json
+```
+
+**Body:**
+```json
+{
+ "message": "Why is this loop infinite?",
+ "history": [],
+ "codeContext": "while(i > 0) { ... }",
+ "fileContext": "",
+ "sessionId": "uuid-v4"
+}
+```
+
+### POST `/api/generate-title`
+Generates a short title for chat sessions.
+
+**Headers:**
+```
+Authorization: Bearer <firebase_id_token>
+Content-Type: application/json
+```
+
+**Body:**
+```json
+{
+ "message": "First user message"
+}
+```
+
+## Deployment
+
+### Render.com
+
+1. Create a new Web Service
+2. Connect your GitHub repository
+3. Set environment variables:
+ - `GEMINI_API_KEY`
+ - `FIREBASE_CREDENTIALS` (full JSON string)
+4. Deploy!
+
+### Frontend (Static Hosting)
+
+Deploy `index.html` to:
+- GitHub Pages
+- Netlify
+- Vercel
+- Any static hosting service
+
+Update the API URL in `index.html`:
+```javascript
+const API_URL = 'https://your-backend.onrender.com/api/chat';
+```
+
+## Development
+
+### Running Tests
+
+```bash
+python test_backend.py
+```
+
+### Code Style
+
+- Python: Follow PEP 8
+- JavaScript: ES6+ with consistent formatting
+- Use meaningful variable names
+- Comment complex logic
+
+## Security Features
+
+✅ Firebase ID Token verification on backend
+✅ CORS protection
+✅ Environment variable protection
+✅ Server-side authentication validation
+✅ Secure API key storage
