+# Izaac 2.1 Project
+
+This project consists of a Django backend and a React/TypeScript frontend. Below are instructions for setting up and running both parts in development mode.
+
+## Prerequisites
+
+- Python 3.x
+- Node.js (LTS version recommended)
+- npm or yarn
+- SQLite (included with Python)
+
+## Backend Setup
+
+1. Navigate to the backend directory:
+```bash
+cd backend
+```
+
+2. Create and activate a virtual environment:
+```bash
+python -m venv venv
+source venv/bin/activate  # On Windows use: venv\Scripts\activate
+```
+
+3. Install dependencies:
+```bash
+pip install -r requirements.txt
+```
+
+4. Run database migrations:
+```bash
+python manage.py migrate
+```
+
+5. Start the development server:
+```bash
+python manage.py runserver
+```
+
+The backend will be available at `http://localhost:8000`
+
+## Frontend Setup
+
+1. Navigate to the frontend directory:
+```bash
+cd frontend
+```
+
+2. Install dependencies:
+```bash
+npm install
+# or if you use yarn:
+yarn install
+```
+
+3. Start the development server:
+```bash
+npm run dev
+# or if you use yarn:
+yarn dev
+```
+
+The frontend will be available at `http://localhost:5173`
+
+## Development
+
+- Backend API documentation is available at `http://localhost:8000/api/docs/` when the server is running
+- Frontend hot-reloading is enabled by default
+- Backend hot-reloading is enabled by default with Django's development server
+
+## Project Structure
+
+- `/backend` - Django backend application
+- `/frontend` - React/TypeScript frontend application
+- `/nginx` - Nginx configuration files
+
+## Additional Notes
+
+- Make sure both backend and frontend servers are running simultaneously for full functionality
+- The backend uses SQLite as the database by default
+- Frontend is built with Vite and uses Tailwind CSS for styling
