 Updating Config and Script Files  
 ******************************** 
 
+You will need to update the following files: 
+ 
+* parm/config/*/config.ufs
+* parm/config/*/config.wave
+* scripts/exgfs_wave_post_gridded_sbs.sh
 
+You will need to add the following files: 
 
+* parm/wave/ww3_grib2.${WAVEGRID}.inp.tmpl
+* parm/wave/${WAVEGRID}_interp.inp.tmpl
 
+For config.ufs: 
 
+If this is a computational you will need to update this file. If this is a new output file you can skip this update.
+There are two sections to update: 
+1. Add the new grid as a possible ww3 resolution at the top of the file 
+2. In the WW3 specific settings section, add a case for the new grid and define ntasks_ww3 (number of tasks for WW3) and 
+if the grid requires a different value of nthreads_ww3 (number of threads) add that to the grid specific case as well. 
+
+For config.wave: 
+
+If this is a computational grid, add a section for the newly added grid in the possible cases for waveGRD, adding the appropriate
+non-default values for this specific grid.  If this is a new output grid, then update all of the waveGRD cases for waveinterpGRD as 
+needed.
+
+
+For scripts/exgfs_wave_post_gridded_sbs.sh and the inp.tmpl files: 
+
+There are two case settings for either interpolated grid output or grib output for a computational grid that should be updated to 
+add to the possible cases for this new grid as appropriate.   If it's a new interpolated grid, you will also need to add a 
+parm/wave/${WAVEGRID}_interp.inp.tmpl file.  See WW3/model/inp/ww3_gint.inp for information about this file.  If it's a new 
+computational grid or just an output grid you will need a new parm/wave/ww3_grib2.${WAVEGRID}.inp.tmpl file.  See the file 
+WW3/model/inp/ww3_grib.inp for more infomration about this input file.  The other existing templated input files can be used 
+as guides to create these new files.

 * Instructions for creating mesh.${WAVEGRID}.nc can be found at https://ufs-weather-model.readthedocs.io/en/latest/InputsOutputs.html#ww3 
 * The ww3_gint.WHTGRIDINT.bin.${WAVEGRID} can be created by running the ww3_gint routine as desired and then saved. 
 
+Once the new fix files have been created, :ref:`open an issue to have the master fix file directory updated<https://github.com/NOAA-EMC/global-workflow/issues/new?assignees=KateFriedman-NOAA%2CWalterKolczynski-NOAA&labels=Fix+Files&projects=&template=fix_file.md>`. This is a separate step than the process to update the workflow below.
