+
+It offers a layout engine designed with a full paging support in mind. The document consists of many simple elements (e.g. border, background, image, text, padding, table, grid etc.) that are composed together to create more complex structures. This way, as a developer, you can understand the behavior of every element and use them with full confidence. Additionally, the document and all its elements support paging functionality. For example, an element can be moved to the next page (if there is not enough space) or even be split between pages like table's rows.

+
+## Simplicity is the key
+
+How easy it is to start and prototype with QuestPDF? Really easy thanks to its minimal API! Please analyse the code below:
+
+```#
+using QuestPDF.Fluent;
+using QuestPDF.Helpers;
+using QuestPDF.Infrastructure;
+
+// code in your main method
+Document.Create(container =>
+{
+    container.Page(page =>
+    {
+        page.Size(PageSizes.A4);
+        page.Margin(2, Unit.Centimetre);
+        page.Background(Colors.White);
+        page.DefaultTextStyle(x => x.FontSize(20));
+        
+        page.Header()
+            .Text("Hello PDF!")
+            .SemiBold().FontSize(36).FontColor(Colors.Blue.Medium);
+        
+        page.Content()
+            .PaddingVertical(1, Unit.Centimetre)
+            .Column(x =>
+            {
+                x.Spacing(20);
+                
+                x.Item().Text(Placeholders.LoremIpsum());
+                x.Item().Image(Placeholders.Image(200, 100));
+            });
+        
+        page.Footer()
+            .AlignCenter()
+            .Text(x =>
+            {
+                x.Span("Page ");
+                x.CurrentPageNumber();
+            });
+    });
+})
+.GeneratePdf("hello.pdf");
+```
+
+And compare it to the produced PDF file:

+The Fluent API of QuestPDF scales really well. It is easy to create and maintain even most complex documents. Read [the Getting started tutorial](https://www.questpdf.com/documentation/getting-started.html) to learn QuestPDF basics and implement an invoice under 200 lines of code. You can also investigate and play with the code from [the example repository](https://github.com/QuestPDF/example-invoice).
