 The following manual will guide you through the process of powering up your UniPi Neuron controller. Before the start, please check the device for any damage that occurred during shipment or any other visible defect.
 ===== OS installation =====

 Prepare an SD card to which the OS will be burned. You can purchase the card in a single package with the controller – if the card was not purchased this way, you need to either purchase one or use your own card. The complete software package requires approximately **2.5 GB**; while a 4GB memory card would be sufficient theoretically, we strongly recommend using an **8 GB** or **16 GB**. The card’s speed is important, we thus recommend to choose a faster card of Class 10 or more.
-After obtaining the card, download the UniPian OS image. In the [[files:software:os-images:00-start|Files & Downloads]] section, you can find the latest release. Download and extract the RAR archive containing a //.img// file to be burned onto an SD card.

The default size is 4 MB – in case of issues, it is also possible to use 1MB size.

 The "dd" program does not indicate its operation, nor displays any information. Writing onto the SD card may take up to 5 minutes; that said, simply wait until some result will display.

 For the purpose of this guide, only several commands will be needed to be entered into the SSH terminal. Bear in mind that it is recommended to paste commands by lines. It is also possible to run several blocks at once, but we strongly recommend to perform the procedure one step at a time. If the UniPian image was used, the EVOK is already contained within it and it is not needed to install it again. It is, however, necessary to check if the latest version is used. All you need to do is to use following commands:
-''sudo su ''
+''sudo su''
-''apt-get install evok ''
+''apt-get install evok''
 ''apt-get update''
