-        The <filename>image_types_uboot</filename> class
-        defines additional image types specifically for the U-Boot bootloader.
+        This class also handles conversion and compression of images.
+        <note>
+            To build a VMware VMDK image, you need to add "wic.vmdk" to
+            <link linkend='var-IMAGE_FSTYPES'><filename>IMAGE_FSTYPES</filename></link>.
+            This would also be similar for Virtual Box Virtual Disk Image
+            ("vdi") and QEMU Copy On Write Version 2 ("qcow2") images.
