+:mod:`mozpower` --- Power-usage testing
+=======================================
+
+Mozpower provides an interface through which power usage measurements
+can be done on any OS and CPU combination (auto-detected) that has
+been implemented within the module. It provides 2 methods to start
+and stop the measurement gathering as well as methods to get the
+result that can also be formatted into a perfherder data blob.
+
+Basic Usage
+-----------
+
+Although multiple classes exist within the mozpower module,
+the only one that should be used is MozPower which is accessible
+from the top-level of the module. It handles which subclasses
+should be used depending on the detected OS and CPU combination.
+
+.. code-block:: python
+
+ from mozpower import MozPower
+
+ mp = MozPower(
+ ipg_measure_duration=600,
+ sampling_rate=1000,
+ output_file_path='tempdir/dataprefix'
+ )
+ mp.initialize_power_measurements()
+
+ # Run test TEST_NAME
+
+ mp.finalize_power_measurements(
+ test_name=TEST_NAME,
+ output_dir_path=env['MOZ_UPLOAD_DIR']
+ )
+
+ # Get complete PERFHERDER_DATA
+ perfherder_data = mp.get_full_perfherder_data('raptor')
+
+All the possible known errors that can occur are also provided
+at the top-level of the module.
+
+.. code-block:: python
+
+ from mozpower import MozPower, IPGExecutableMissingError, OsCpuComboMissingError
+
+ try:
+ mp = MozPower(ipg_measure_duration=600, sampling_rate=1000)
+ except IPGExecutableMissingError as e:
+ pass
+ except OsCpuComboMissingError as e:
+ pass

+
+MozPower Interface
+------------------
+
+The following class provides a basic interface to interact with the
+power measurement tools that have been implemented. The tool used
+to measure power depends on the OS and CPU combination, i.e. Intel-based
+MacOS machines would use Intel Power Gadget, while ARM64-based Windows
+machines would use the native Windows tool powercfg.
