+
+Within this folder, there are 3 python files:
+* A clip maker of satellite's orbit and attitude in 3D space (ClipMakerOfTumbling.py)
+* Simulation of satellite's astrodynamics and antenna model (SimulationOfTumbling.py)
+* Implementation of a BEC and zfec (ErasureCorrectingCode.py)
+
+The input to all of the previous files is a yaml file, and it is found in the following repository:
+Python/SatelliteTumbling/data/input.yaml
