+# **MARLIN** Box
+This project aims to take another approach at RFID-Jukeboxes like the [toniebox](https://tonies.com/).
+
+Our goal is to empower parents to make their kids happy - on their own terms.
+
+## Prerequisites
+We are currently at the beginning of the development.
+
+If you wish to try the **MARLIN** Box in this state you will need the following:
+- Raspberry Pi (at least 3B)
+  - Raspbian OS
+    - Packages:
+      - `portaudio-devel.x86_64`
+- RFID-Reader (**EM4100**)
+- Some **.mp3-Files**
+
+## Setup
+- Clone this repository to your Computer or directly onto the Raspberry Pi - on whatever device you would like to build the software you will need **golang** installed
+  - `git clone https://github.com/itsscb/marlinbox`
+  - `cd marlinbox/cmd`
+- Build the software
+  - `go build main.go && mv main marlinbox`
+- Create or modify the file `playlist.json` in the same directory 
+- Run it with `sudo` [^1]
+  - `sudo ./marlinbox`
+
+[^1]: Required because we access `/dev/input/` devices which require root privileges.
