 ### AeroDisk
-_AeroDisk_ is a new module for a disk actuator aerodynamic module.  This module assumes a rigid disk with only a few degrees of freedom for modeling turbine aerodynamics with a simple actuator disk.  This is useful for modeling turbines that are not of interest in very large wind farms modeled by _FAST.Farm_, but whose wake dynamics are needed for turbines further into the wind farm that are of interest.  We do not recommend using this module with standalone _OpenFAST_ simulations.
+_AeroDisk_ is a new module for a disk actuator aerodynamic module for modeling turbine aerodynamics as a simple actuator disk. This module assumes that the rotor is a rigid disk, and so, should be not be combined with _BeamDyn_ or _ElastoDyn_ with blade degrees of freedom enabled; it is meant to be used with the new _Simplified-ElastoDyn_ module.  This is useful for modeling turbines that are not of interest in very large wind farms modeled by _FAST.Farm_, but whose wake dynamics are needed for turbines further into the wind farm that are of interest.  We do not recommend using this module with standalone _OpenFAST_ simulations.

 ### AeroDyn
-_AeroDyn_ improvements include a new input file, nacelle drag, visualization improvements, unsteady aero for tailfins, multi-rotor support in the driver and interface library, a simple ground effect model for _OLAF_ wakes, using _InflowWind_ pointers for data access, and many bug fixes.  With the removal of _AeroDyn14_, _AeroDyn15_ is now simply referred to as _AeroDyn_ in the input files and code (documentation may not be fully updated).
