+# Reading and printing the device configuration
+# =============================================
+# This demo demonstrates how to access and inspect the configuration of a
+# PicoQuant time tagging device with snAPI.
+#
+# The script initializes the device, loads an ini configuration file, and then
+# prints the complete device configuration structure. This structure contains
+# device information as well as the current settings of the input channels.
+#
+# Setup:
+# The device type is selected by the ini file loaded with `loadIniConfig`. The
+# example uses `config\MH.ini`, which should be replaced by the configuration
+# file matching the connected device and measurement setup.
+#
+# After loading the configuration, the script reads selected entries from
+# `sn.deviceConfig`, such as the device ID, the trigger or discriminator levels
+# of all channels, and the enable state of a selected channel.
+#
+# This is useful for checking whether a device has been configured correctly,
+# verifying channel settings before a measurement, and learning how to access
+# configuration values programmatically for use in custom scripts.
