         .AddDocument(doc => 
             doc.SetBody(GetBody()).SetFooter(GetFooter())
         ).WithDimensions(dims =>
         {
             dims.SetPaperSize(PaperSizes.A3)
                 .SetMargins(Margins.None)
                 .SetScale(.99);
         }).WithAsyncAssets(async assets => assets.AddItem("some-image.jpg", await GetImageBytes()));

     var req = await builder.BuildAsync();

     var result = await sharpClient.HtmlToPdfAsync(req);

     return this.File(result, "application/pdf", "gotenbergFromHtml.pdf");
 }

Url To Pdf

Url to Pdf with custom page range, header & footer:

public async Task<Stream> CreateFromUrl(string headerPath, string footerPath)
{
	var builder = new UrlRequestBuilder()
		.SetUrl("https://www.cnn.com")
		.ConfigureRequest(config =>
		{
			config.SetPageRanges("1-2");
