-# Regional workflow
+# Regional Workflow
+
+**The regional workflow in this repository can no longer be run in a stand-alone configuration. To clone the end-to-end system, build the code, and run the workflow, see:**
 
-This is the community\_develop branch of the regional\_workflow used to run the stand-alone regional (SAR) version of FV3.
+https://github.com/ufs-community/ufs-srweather-app/wiki
 
-## Check out and build the regional workflow:
-
-1. Check out the regional workflow external components:
-
-`./manage_externals/checkout_externals`
-
-This step will checkout EMC\_post, NEMSfv3gfs and its submodules, UFS\_UTILS\_chgres\_grib2 and UFS\_UTILS\_develop in the sorc directory.
-
-2. Build the utilities, post and FV3:
-```
-cd sorc
-./build_all.sh >& out.build_all &
-```
-NOTE: You must *not* have the conda module loaded for the build to succeed.
-
-This step will also copy the executables to the `exec` directory and link the fix files.
-
-4. Create a `config.sh` file in the `ush` directory (see Users Guide).
-
-5. Set up your python environment; you will need python3, and it must have the 'PyYAML', 'Jinja2', and 'f90nml' packages installed
-
-On some platforms this environment is already available with a few commands;For example, on Jet/Hera:
-```
-cd ush
-module use -a /contrib/miniconda3/modulefiles
-module load miniconda3
-conda activate regional_workflow
-```
-on Cheyenne:
-```
-cd ush
-ncar_pylib /glade/p/ral/jntp/UFS_CAM/ncar_pylib_20200427
-```
-
-6. Generate a workflow:
-```
-generate_FV3SAR_wflow.sh
-```
-This will create an experiment directory in `$EXPT_SUBDIR` with a rocoto xml file FV3SAR_wflow.xml. It will also output information specific to your experiment.
-
-7. Launch and monitor the workflow:
-```
-module load rocoto/1.3.1`
-cd $EXPTDIR
-rocotorun -w FV3SAR_wflow.xml -d FV3SAR_wflow.db -v 10
-rocotostat -w FV3SAR_wflow.xml -d FV3SAR_wflow.db -v 10
-```
-8.  For automatic resubmission of the workflow, the following can be added to your crontab:
-```
-*/3 * * * * cd $EXPTDIR && ./launch_FV3SAR_wflow.sh
-```
+This repository contains the regional workflow used to run the end-to-end UFS Short-Range Weather App.
+This system includes pre-processing tasks, the regional UFS Weather Model, and the Unified Post Processor (UPP).
+The workflow is a component of the UFS Short-Range Weather App umbrella repository.
