+
+			<p>
+				The APEX user manual combines a set of guides and howto documents, all supporting the use of APEX.
+				The guides and howto documents are provided as integrated documentation in the APEX site.
+				Furthermore, we provide stand-alone documents in HTML and PDF.
+			</p>
+
+			<p>
+				Note: most of the documentation is written in AsciiDoc.
+				We are using the AsciiDoctor version.
+				Due to the different build tools used for the different documentation targets, the rendered documents differ in style.
+				The content however comes always from a single, normative source located in the APEX source repositories.
+			</p>
