Enter a board title and description, and upload a suitable cover picture. If the picture is on your computer, click the "Upload" button, and select the appropriate file. If the image is online, enter the URL in the "Cover URL" field instead. Please note that you are not allowed to share content that you do not own the rights to. The picture will be displayed in the preview area where you can select which part of it is shown in the board preview. By default, the picture will also be shown as a fullscreen background for the board content. If you want a plain background, uncheck the "Fullscreen background" checkbox. When you are done, press "Save" and go to the next step.
