You can upload documents by dragging them onto the central area or click on ( + ) or [ Add Files ] and select the relevant files from your computer. You can select and upload more than one file at the same time.
The list on the right are the documents that your customer is looking for. Perhaps you don’t have all (yet). In this case it’s important to upload what you already have. You can upload *.PDF, *.png, *.jpg. You have to convert *.doc and *.xls to *.PDF first.
Have you selected your files? press [ Start upload ].
