+## Program Input
+Input data must be entered through a comma-separated values (.csv) and the columns must be like this:
+
+| process_id | arrival_time | cpu_time1 | io_time | cpu_time2 |
+| :---: | :---: | :---: | :---: | :---: |
+| 1 | 1 | 2 | 3 | 4 |
+| 2 | 12 | 3 | 4 | 1 |
+| 3 | 5 | 4 | 5 | 3 |
+| 4 | 13 | 4 | 5 | 15 |
+| 5 | 13 | 5 | 6 | 7 |
 
+you can see and download test file **<a href="test/process_input_data.csv">here</a>**
+
+## Program Output
+1. the program will process the processes and will calculate these information:
+ - Response Time
+ - Turnaround Time
+ - Waiting Time
+ - Process' Start Time
+ - Process' End Time
+2. after running the algorithms for each processes these parameteres will be shown for the algorithm: 
+ - Total Time and Idle Time
+ - Average Waiting Time
+ - Average Response Time
+ - Average Turnaround Time
+ - CPU Utilization
+ - Throughput
