Press Download on any document that YourCA lays out, then tick Add a cover page and press Download as usual.
The cover carries your logo at the top left and what the document is at the top right. The title and the job are in the middle, and the facts are in a panel at the foot, followed by your business details.
A fact with nothing in it is left off the cover, so the panel only shows what the document holds. To reads as Prepared for, and your business follows it as Prepared by.
A pack is ticked for you, because a pack usually goes as one file: the claim pack, the quote and the drawing comparison. Untick it if you do not want the cover.
The tick is offered on PDF and Word. A spreadsheet has no cover. A file the server writes in Word is offered no tick, because that file is written whole on the server.
The cover names your business, never YourCA, like every other page of the document.
