+Basic testing with cam utility
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``cam`` utility can be used for basic testing. You can list the cameras
+detected on the system with ``cam -l``, and capture ten frames from the first
+camera and save them to disk with ``cam -c 1 --capture=10 --file``. See
+``cam -h`` for more information about the ``cam`` tool.
+
+In case of problems, a detailed debug log can be obtained from libcamera by
+setting the ``LIBCAMERA_LOG_LEVELS`` environment variable:
+
+.. code::
+
+    :~$ LIBCAMERA_LOG_LEVELS=*:DEBUG cam -l
+
 Using GStreamer plugin
