+
+    You can use the Memcheck tool included in the
+    \l{http://valgrind.org/info/tools.html}{Valgrind tool suite} to detect
+    problems that are related to memory management in applications.
+
+    \note Memcheck is supported on Linux and Mac OS.
+
+    After you download and install Memcheck, you can use it from Qt Creator.
+    To analyze applications, select \gui {Debug > Start Analyzer > Start}.
+    While the application is running, Memcheck checks all reads and writes of
+    memory and intercepts calls that allocate or free memory or create or
+    delete memory blocks.
+
+    If problems are found, they are listed in the \gui Analysis output pane.
+    Select a link to move to the problematic code.
