    "# Airfoil Analysis\n",
    "# with [AeroSandbox](https://github.com/peterdsharpe/AeroSandbox) and [Manganite](https://github.com/LCL-CAVE/manganite)\n",
    "\n",
    "## Description\n",
    "\n",
    "The Airfoil Design Demonstration Dashboard is a web-based showcase that provides a glimpse into the capabilities of airfoil analysis within a browser environment. It is built upon the open-source repository [AeroSandbox](https://github.com/peterdsharpe/Automotive-Airfoil-Design/) and serves as a demonstration of what's possible in the realm of virtual airfoil exploration.\n",
    "\n",
    "### Key Features\n",
    "\n",
    "1. **Geometry Visualization:** Explore an interactive airfoil geometry, pre-defined for demonstration purposes. Observe how changes in shape and size can impact aerodynamic behavior.\n",
    "\n",
    "2. **Simplified Angle of Attack:** Adjust the angle of attack within a limited range to see the immediate effects on lift and drag forces. \n",
    "\n",
    "3. **Kulfan Coordinates:** This demonstration employs Kulfan coordinates for the representation of airfoil shapes, providing insight into how airfoil data can be structured and analyzed.\n",
    "\n",
    "4. **Basic Constant Display:** View simplified constant values such as lift coefficient (CL), drag coefficient (CD), and moment coefficient (CM).\n",
    "\n",
    "5. **Visualization:** Visualize how changes in airfoil geometry and angle of attack influence aerodynamic characteristics."
