+Infinite8 device library for use in SDKs
+
+# I8DeviceDLL
+
+I8DeviceDLL is a library package for a 3rd party to be able make use of Infinite8 Devices without any desctop application.
+There is some classes and methodes in this dll file for users to minimize complexiti of hardware protocols.
+With this pakage users can easily connect to any Infinite8 devices from many programming languege including C++, matlab and python.
+
+## Getting Started (python)
+
+This dll requires the following packages to work fine.
+
+### Prerequisites
+
+Use pip script to install `scipy` , `numpy`and `pythonnet` . These packages are used to read .dll files writen in C# and calculate some anticipated data.
+```
+pip install scipy
+pip install numpy
+pip install pythonnet
+```
+
+### import dll file
+
+After installing the requrment packages, import ".net for python" (clr) and make a reference (copy) of the .dll file with this commands: 
+
+```
+import clr
+clr.AddReference(the absolute path of i8.dll file)
+# for example: clr.AddReference('C:/Users/i8-tech/Desktop/csharp_dlls/infinite8dll/I8Library1/bin/Debug/I8Library1.dll')
+```
+### instance from main class of i8devices
+```
+just import `Device` class, And then you can use it by declaring an instance of `Device` class.
+
+```
+## How to Use
+
+First of all, you should plug your device into your PC, and also install `ST micro COM Port Package` from `Device Manager`.
+After that 
+
+```
+file_base = FileBase(subject_id=1, protocol_name='room_1', task_name='SART', sequence="", project='1', description='hi')
+file_base.set_brain_data(raw_data, channel_count, sample_count, sample_rate) # All fields are numeric. 
+file_base.set_device_data(device_name, software_version, firmware_version, sensor_name) # Use standard patterns like what you can see on the server.
+file_base.set_extra_signal(raw_data, channel_count, sample_count, sample_rate) # All fields are numeric. 
+file_base.set_output_data(raw_data, channel_count, sample_count, sample_rate) # All fields are numeric. 
+file_base.set_reaction_data(feedback, label, correct_answers)        
+file_base.save("path:\\to\\place\\you\\want\\to\\save\\file")
+```
+
+Use the following methods to retrieve class information:
+
+```
+# trial data
+    file_base.get_subject_id()
+    file_base.get_protocol_name()
+    file_base.get_task_name()
+    file_base.get_description()
+    file_base.get_sequence()
+    file_base.get_project()
+    file_base.get_timestamp()
+    file_base.get_filename()
+
+# output data
+    file_base.get_output_raw_data()
+    file_base.get_output_channel_count()
+    file_base.get_output_sample_count()
+    file_base.get_output_sample_rate()
+
+# extra data
+    file_base.get_extra_raw_data()
+    file_base.get_extra_channel_count()
+    file_base.get_extra_sample_count()
+    file_base.get_extra_sample_rate()
+
+# brain data
+    file_base.get_brain_raw_data()
+    file_base.get_brain_channel_count()
+    file_base.get_brain_sample_count()
+    file_base.get_brain_sample_rate()
+    file_base.get_brain_quality()
+ 
+# device and sensor
+    file_base.get_device_info()
+    file_base.get_sensor_name()
+ 
+# reaction data
+    file_base.get_feedback_data()
+    file_base.get_label_data()
+    file_base.get_reaction_data()
+```
