+                If you have not used \QC before, and want to become familiar

+            \i  \l{Building and Running an Example Application}
+
+                To check that \l{glossary-development-target}{targets} were
+                successfully installed as part of the \QSDK installation, open
+                an example application and run it. If you have not done so
+                before, go to \l{Building and Running an Example Application}.
