     \title Importing 2D Assets
 
+    You can import 2D assets, such as images, fonts, and sound files, to \QDS to
+    use them in your projects.
+
+    To import an asset, drag-and-drop the external file containing the asset from,
+    for example, File Explorer on Windows, to \uicontrol {Form Editor},
+    \uicontrol Navigator, or \uicontrol {Text Editor}. Alternatively, select
+    \l Library > \uicontrol Assets > \inlineimage plus.png
+    and follow the instructions in the \uicontrol {Asset Import} dialog. You can
+    also multiselect several external asset files to drag-and-drop them to
+    \QDS simultaneously.
+
+    The imported images will appear in \uicontrol Library > \uicontrol Assets.
+    If you initiate the import by dragging the assets to \uicontrol {Form Editor},
+    they are also added to your projects as image components, and you can view
+    them in \uicontrol {Form Editor} and \uicontrol Navigator. If you drag an
+    external font file to \uicontrol {Form Editor}, it will be added to your
+    project as a text component. Other imported assets, such as sound files,
+    will only appear in \uicontrol Library > \uicontrol Assets, and you can then
+    drag-and-drop them to a suitable view.
