-**Quick Setup using a Virtual Machine (recommended for this Tutorial)**
-
-* Install and set up [git](https://help.github.com/articles/set-up-git/)
-* Install latest [VirtualBox](https://www.virtualbox.org/wiki/Downloads) & [VirtualBox Extension Pack](https://www.virtualbox.org/wiki/Downloads) for **your system**
-* Install [Vagrant](https://www.vagrantup.com/downloads.html)
-* Linux, OSX:
-    ```Shell
-    git clone --recursive https://github.com/RIOT-OS/Tutorials
-    cd Tutorials
-    ```
-* Windows:
-    * set
-      ```Shell
-      git config --global core.autocrlf input
-      ```
-      before cloning
-    * clone the `Tutorials` and the `RIOT` submodule as follows:
-    ```Shell
-    git clone https://github.com/RIOT-OS/Tutorials
-    cd Tutorials
-    git submodule update --init --recursive
-    ```
-* In case a virtual machine is disseminated locally, adapt the path for the vagrant box `vagrant box add RIOT/ubuntu1804 <path to box>`
-* Run `vagrant up` and `vagrant ssh` afterwards. See the [Vagrant RIOT Setup](https://github.com/RIOT-OS/RIOT/blob/master/dist/tools/vagrant/README.md) for a more general explanation.
-
-**Regular Setup without using a VM (recommended for RIOT developement)**
-
-* Install and set up [git](https://help.github.com/articles/set-up-git/)
-* Install the build-essential packet (make, gcc etc.). This varies based on the operating system in use.
-* Install [Native dependencies](https://github.com/RIOT-OS/RIOT/wiki/Family:-native#dependencies)
-* Install [OpenOCD](https://github.com/RIOT-OS/RIOT/wiki/OpenOCD)
-* Install [GCC Arm Embedded Toolchain](https://launchpad.net/gcc-arm-embedded)
-* On OS X: install [Tuntap for OS X](http://tuntaposx.sourceforge.net/)
-* [additional tweaks](https://github.com/RIOT-OS/RIOT/wiki/Board:-Samr21-xpro) necessary to work with the targeted hardware (ATSAMR21)
-* Install `netcat` with IPv6 support (if necessary)
-
-  ```bash
-  sudo apt-get install netcat-openbsd
-  ```

-## Troubleshooting
-
-### If you get the following error after running `vagrant up`
-
-> The guest machine entered an invalid state while waiting for it to boot. Valid states are 'starting, running'. The machine is in the 'poweroff' state.
-
-Make sure you have the [Extension Pack](https://www.virtualbox.org/wiki/Downloads) installed.
-
-### If you cannot flash a connected board (`/dev/ttyXXXX` does not exist)
-
-Make sure your user is a member of the usergroup `vboxusers`. On Linux you can add the current user with
-
-`usermod -a -G vboxusers $USER`.
-
-You can check the groups of your user with
-
-`groups`.
-
-Note that you need to log out once to reload a Linux user's group assignments
