 ## Input and Output
 
-s
+The input needs a configuration file named settings.ini , which contains the physical properties and numerial parameters for the simulation, and files containing the positions of the molecules. Optionally a file containing the initial velocity of the particles can also be provided. 
+
+The output contains the position and velocities of the molecules. Optionally the angle of rotation of particles, and forces related to intermolecular interactions can also be extracted.
+
+## Postprocessing
+
+The program automatically converts the .csv results to VTK, so one may use this result to postprocess on paraview. 
+Some python scripts are provided to calculate concentration, distribution entropy, viscosity and  other things. The theory behind these program is summarized at the Master Thesis that will be published soon.
