+## General Information
+The script was created to detect abnormalities between two different osi files. 
+The first file is treated as a benchmark for the second file. 
+
+
+## Usage
+
+The script should be run with python 2.7.
+The script expect at least two positional arguments. Both of those are osi-encoded messages.
+Thi first file is treated as a benchmark.
+
+It can be run using the following command. 
+./compare_data.py input.txt input_2.txt 
+Because the parsing of the file takes significant amount of time it is recommended, at least for the initial tests, to restrict number of read messages.
