+Plugins devoted to National Instruments signal acquisition and generation, using the NI-DAQmx driver through the
+``nidaqmx`` package of National Instruments (`documentation <https://nidaqmx-python.readthedocs.io/en/stable/>`_).
+They include a ``NIDAQmx`` actuator for signal generation, a 0D viewer for quick measurements and a 1D viewer for data
+acquisition as a function of time, and the ``NIDAQmx`` object (``hardware/national_instruments/daqmxni.py``) to build
+your own plugin on.
+
+Difference with the pydaqmx branch
+==================================
+
+The repository has two lines of plugins, which use two different Python interfaces to the same NI-DAQmx driver. They
+do not share their instrument plugins (``NIDAQmx`` here, ``DAQmx_...`` there).

+   * - State
+     - the ``NIDAQmx`` viewers were tested with a cDAQ-9174 and a USB-6341 (modules NI-9205, NI-9211, NI-9217); the
+       ``NIDAQmx`` actuator is not finished yet (its movements still raise ``NotImplementedError``)
+     - the ``PyDAQmx`` based plugins, kept as they are
+
+This branch still contains the ``PyDAQmx`` based ``DAQmx`` object and the user guides of the photon counter and the
+scanner control, but not the instrument plugins of the ``pydaqmx`` branch: use that branch if you need them.
+
+Requirements
+============
+
+* PyMoDAQ >= 5.3.7
+* the NI-DAQmx driver of National Instruments, installed on the computer connected to the device (use NI MAX to test
+  your hardware). Where the driver cannot be found, the modules of this plugin are not usable and PyMoDAQ skips them.
+* the ``nidaqmx`` and ``pydaqmx`` Python packages, installed with the plugin.
