# Yodeck digital signage player
Every Hololuminescent display (HLD) comes with a demo media player (a Raspberry Pi 4) that runs our own software. This software is built to run videos on an inserted USB thumb drive, and it runs entirely offline. It is not intended to be a fully managed digital signage solution.
[Yodeck](https://www.yodeck.com/) provides a digital signage solution that can handle fleet deployment and content management. You can set up Yodeck on the computer that comes with the HLD to create a full digital signage solution. This guide will walk you through that process.
## Step 1: Flash your SD Card with Yodeck OS
1. Take the SD card out of the included Raspberry Pi 4 — it is located on the left side of the device, and you may need tweezers to remove it
2. Insert it into your computer (directly or via a USB adapter) — ensure it is unlocked
3. Download the [Yodeck OS Image](https://player-image.yodeck.com/RaspberryPi_Yodeck.zip?_gl=1*1ngrum7*_gcl_aw*R0NMLjE3NjA2Mzk1MzMuQ2p3S0NBandyOExIQmhCS0Vpd0F5NDd1VWhiZkFQcWo2cTRIdlp0WVNIVEp5Vi1fMTNZMjRKSmxDOGE4WlJWTmdEV0hNeXJkSHBzSEN4b0NWb3dRQXZEX0J3RQ)
4. Unzip the compressed archive
5. Download and install [Balena Etcher](https://etcher.balena.io/#download-etcher)
6. Open Balena Etcher
7. Select “Flash from File”
8. Select the Yodeck .img file
9. Under “Target” select the SD card
10. Click “Flash”
11. Ignore or dismiss any OS warnings about the drive
12. Even if it says there was an error during validation, the flashing process is typically complete
## Step 2: Set Up Yodeck Player
1. Insert the SD card into the included Raspberry Pi 4
2. Connect the player to the internet using an Ethernet cable — the port is on the right side of the device
3. Power on the device — you should see the Yodeck logo appear, rotated on the screen
4. Let the Yodeck player update
5. Once the player has updated, it will show a registration number
6. Go to the Yodeck web app on your browser:
7. Sign in or create an account
8. Under “Screens” select “Add Screen” — if you’re adding a screen through the Yodeck “Welcome” page, you must first select “Connect your player”
9. Select “Yodeck Player” and add it
10. Enter the registration number
11. Your screen should now be active and ready to receive content
## Step 3: Create a Playlist
1. Under “Media” select “Videos”
2. Select “Add Videos”
3. Upload your HLD videos
4. IMPORTANT! In the video settings, toggle on “Rotate Video” and select 270°
5. Select “Save” and let the videos process
6. Once this is finished, you can create a playlist by selecting “Playlists”
7. Select “Add Playlist”
8. Select “Classic” and click “Add”
9. Give your playlist a name
10. Add content from your media library into the playlist timeline
11. Select “Save”
## Step 4: Push a Playlist to your HLD
1. Go to “Screens”
2. Select the HLD you want to send your playlist to
3. Under “Screen Content” select “Playlist”
4. Select the playlist you want to deploy and click “Ok”
5. Select “Save”
6. Select “Push to Screens” on the top right of the screen
7. Select “Push Now”
8. After some processing, your new playlist will start playing on your HLD
