+# DHBW-Service-App
+
+## Introduction
+This is a project by three students of the Cooperative State University in Karlsruhe (DHBW Karlsruhe).
+The goal is to develop a native iOS app providing easy and straightforward access to services like RaPla, Dualis and the canteen plan.
+
+<b>Disclaimer:</b> This project is not affiliated with the DHBW Karlsruhe
+
+## Build it yourself
+As the app is not yet available on the App Store, you can build and install it yourself if you have a Mac with Xcode installed.
+Just clone the repository, then open the project in Xcode and navigate to the project settings. In the target section, select
+the iOS target. Then you have to select your own development team in the dropdown or create a new one.
+If you completed these steps, you should be able to install a development version of the app on your own devices.
