 ### Available Example Measurements
 
-- `sample_measurement`: Performs a loopback measurement with various data types. Provides a Measurement UI and a LabVIEW UI.
-- `nidaqmx_analog_input`: Performs a finite analog input measurement with NI-DAQmx.
-- `nidcpower_source_dc_voltage`: Sources and measures a DC voltage with an NI SMU. Provides a Measurement UI and a LabVIEW UI.
-- `nidmm_measurement`: Performs a measurement using an NI DMM.
-- `nifgen_standard_function`: Generates a standard function waveform using an NI waveform generator.
-- `niscope_acquire_waveform`: Acquires a waveform using an NI oscilloscope.
-- `niswitch_control_relays`: Controls relays using an NI relay driver (e.g. PXI-2567).
-- `nivisa_dmm_measurement`: Performs a DMM measurement using NI-VISA and an NI Instrument Simulator v2.0.
-- `game_of_life`: Displays Conway's Game of Life in a graph. Shows measurement cancellation and updating the UI during a measurement.
