+\example applicationmanager/process-status
+\title Displaying Information About Application Processes
+\image process-status-example.png
+\brief How to use ProcessStatus to display application process information.
+\ingroup applicationmanager-examples
+
+This example shows you how to use the \l ProcessStatus component to display information
+about an application's process.
+
+This example is based on the simpler \l {"Hello World!" System-UI Example} {Hello World} one. You might
+want to start from there if you haven't seen it already.
+
+On the left side the built-in applications are listed in a column, where each application has a row containing
+its icon and name next to a tabbed view that shows information about the application's process (in case the
+application is actually running).
+
+On the right side of the System-UI the windows of the running applications are stacked in a column, in order of
+appearance (oldest window at the top and youngest at the bottom).
+
+There are three applications available, a red one called "CPU Hog" which consumes a lot of CPU, a green one
+called "Memory Hog" that continually increases its memory consumption (so don't leave it running for too long
+as it will eat up all available RAM eventually) and a blue one called "Slim", which behaves normally.
