+Installing
+----------
+The virtual appliance can be imported into [VirtualBox](https://www.virtualbox.org/ "VirtualBox"). You will need the extention package of virtual box to be able to use the USB device. Go to [Oracles download page](https://www.oracle.com/virtualization/technologies/vm/downloads/virtualbox-downloads.html?msclkid=be59f68fcf9f11ec801dcf4ea944dd1d) to install both virtual box and the expansion pack.

+* [Gnome Boxes](https://wiki.gnome.org/Apps/Boxes)
+* [VM Player](http://www.vmware.com/products/player/ "WM Player")
+
+Using the virtual machine
+-------------------------
+After importing just run the machine. It logs in automatically but use the following credentials if needed:
+```
+User: bitcraze
+Pass: crazyflie
+```
+
+Optimizing for Use
+-------------------------
+For faster USB connection with the Crazyradio PA it is advised to filter the USB device at startup of the VM. Go to *settings->USB*, make sure that USB 3.0 is enabled and add a USB device filter for the Crazyflie PA, which should be called 'Bitcraze Crazyradio PA USB Dongle [9955]'.
+
+Also just to be sure, install the guest addition pack from inside the VM by typing: 
+`sudo apt-get install virtualbox-guest-additions-iso`
+
+For the rest of the performance of your VM, you can try to increase the base memory (Settings/System/Motherboard), the CPU's available (Settings/System/Processor), enable hardware acceleration and select Hyper-V (Settings/System/Acceleration) or increase the video memory with 3D acceleration enabled (Settings/Display/Screen). This requires some adjusting as this could be different per system you are running the VM from.
