 # Platform Management
+
+## Platform Fan and Thermal Management
+
+The underlying platform implementation provides the ONLP core with the Fan and Thermal management algorithm.
+Calls to this code are handled automatically by the platform daemon and are not generally used by ONLP applications.
+
+## Platform Debug Hooks
+
+The application may call the debug hook ```onlp_platform_debug()``` to issue platform-specific debug commands to the lower layer software.
+These are completely optional and depend entirely on the system integrator.
+
+This is generally used for interactive debugging -- for example you might want to dump the contents of all of the system CPLD registers in order to
+examine them directly in the case of system debugging or technical support.
+
+While you can call this API it is usually invoked via the command line tools.
