+Prerequisites 
+===============
+In order to use the **nidaqmx** package, you must have at least one DAQ
+device installed on your system. Both physical and simulated devices are supported. The
+examples below use an X Series DAQ device of PCIe-6320 You can use **NI MAX** or **NI Hardware Configuration Utility** to
+verify and configure your devices.
+
+Finding and configuring device name in **NI MAX**:
