-The Global Workflow supporting the Global Forecast System (GFS) and Global Ensemble Forecasting System (GEFS) with the [UFS-weather-model](https://github.com/ufs-community/ufs-weather-model) and both [GSI](https://github.com/NOAA-EMC/GSI)- and [GDASApp (JEDI)](https://github.com/NOAA-EMC/GDASApp)-based Data Assimilation systems.
+The Global Workflow supporting the Global Forecast System (GFS) and the Global Ensemble Forecasting System (GEFS) with the [UFS-weather-model](https://github.com/ufs-community/ufs-weather-model).  Data assimilation, currently only available for the GFS, is provide by both the [GSI](https://github.com/NOAA-EMC/GSI)- and [GDASApp (JEDI)](https://github.com/NOAA-EMC/GDASApp)-based Data Assimilation systems.
 
 In progress [documentation](https://global-workflow.readthedocs.io/en/latest/) is available.
 
+# Prerequisites
+
 The Global Workflow depends on the following prerequisities to be available on the system:
 
 * Workflow Engines - [Rocoto](https://github.com/christopherwharrop/rocoto) and [ecFlow](https://github.com/ecmwf/ecflow) (for NWS Operations)
 * Compiler - Intel classic compiler suite version 2021.x
 * Software - NCEPLIBS (various), ESMF, HDF5, NetCDF, and a host of other softwares (see module files under /modulefiles for additional details).
     - [Spack-stack](https://github.com/JCSDA/spack-stack) is recommended for the installation of dependent libraries.
