+  <h2>Technology demonstration for 3D simulation of Brunsviga RK 13</h2>
+</div>
+
+This repository is a demonstration of web technologies that might be used for simulating the Brunsviga RK 13 mechanical calculator.
+The demo is designed to be small and lightweight in deploment.
+
+We use `vite` as the build system for a `react.js` web application that makes use `three.js` WebGL capabilites in order to render 3D objects and animate them in realtime.
+Typescript is the preferred language as it offers relative type-safety during development.
+The user interface is styled with `tailwindcss` and will refer to the paper, source code and some refernce documentation for the Brunsviga RK 13.
+
+The built application can be delpoy via a static web server such as Nginx (see docker container).
+
+## ☁️ Technology Stack
+
+- Vite
+- React
+- Tailwind CSS
+- Three.js
+
+## 🚀 Getting Started
+
+In order to get started, clone the repository:
+```
+git clone https://git.montehaselino.de/servostar/brunsviga-demo.git
+```
+
+Then build compile the application and run in development mode:
+```
+npm ci && npm run dev
+```
+
+## 🐋 Docker Container
+
+The application can be build and launched in a multi stage container:
+```
+docker build --tag brunsviga-demo:latest .
+```
+
+Then run the container on port 80:
+```
+docker run -p 80:80 brunsviga-demo:latest
+```
