# VAN PI DOCS OVERVIEW he VanPi system is meant to be an Open-Source DIY Camper-Van project. So if you are going to build your very own camping van, feel free to give it a try and participate! We offer [forums](https://forum.pekaway.de/) and a [demo](https://demo.pekaway.de/) for the frontend! Demo data is randomly generated every 3min, so basically all the graphs are kinda nonsense... Yet good enough to get the general idea! It is only the frontend though, you can not get a hold of the backend in the demo. By now, we offer an Open-Source image for the Raspberry Pi 4 (see [Downloads](https://downloads.vanpi.de/)) and several hardware in [our shop](https://pekaway.de/collections/alle-produkte). The software is mostly based on Node-RED and can therefore be individually adjusted and extended. Feel free to have a look around, try the image and hit us up with any question you may have! --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
