 ## List of Configuration Files per Package
+Each package provides some additional simulation functionality. To use package in an experiment, we must declare it in  `code/pacakge.conf`. This tells the MITgcm to compile a model.
+In   `input/data.pkg` we activate the package to use it in run-time.
+
+The package-specific parameterization takes place in similar configuration files, which are already mentioned above. 
+Note: Some packages don't feature some types of configuration files. The table below gives an overview, which type of configuration file is present in each package.
