1. go to download https://github.com/3liz/qgis-wfsOutputExtension/releases/latest and download the wfsOutputExtension.1.x.x.zip file
2. extract the wfsOutputExtension folder from zip file and put into C:\OSGeo4W\apps\qgis-ltr\plugins\ (ie, you'll end up with this folder: C:\OSGeo4W\apps\qgis-ltr\plugins\wfsOutputExtension\)
3. backup the existing definitions.py file
4. open the definitions.py file in a text editor and append the following text to the bottom:

       GeoJSON = Format(
           content_type='application/x-geojson',
           filename_ext='geojson',
           force_crs=None,
           ogr_provider='GeoJSON',
           ogr_datasource_options=(),
           zip=False,
           ext_to_zip=(),
       )

5. check that the text starting with GeoJSON aligns horizontally with the closing bracket above it - then save the file
6. open IIS > select server > Fast CGISettings > qgis_mapserv.fcgi.exe > Edit > Environment variables, and confirm that there is an environment variable for DEBUG_WFSOUTPUTEXTENSION=1 (see here for more information) - if not, add it
7. in IIS, recycle the PoziQgisServer application pool

Other OGR formats can be similarly added. See https://gdal.org/drivers/vector/index.html for a complete list of available formats.

        <insert output file extension> = Format(
            content_type='application/x-<insert output file extension>',
            filename_ext='<insert output file extension>',
            force_crs=None,
            ogr_provider='<insert name from "Short name" column from OGR table linked above>',
            ogr_datasource_options=(),
            zip=False,
            ext_to_zip=(),
        )

For any PC from which QGIS projects will be created and maintained, configure QGIS with Font Awesome.

Right-click on C:\OSGeo4W\osgeo4w-setup.exe file, and "Run as administrator". Accept all defaults.

If the setup file doesn't exist at that location, download it from https://trac.osgeo.org/osgeo4w/.

During the update process, if the installer displays a message about files being locked, stop the IIS application pool.

IIS > Server Name > Application Pools > PoziQgisServer - right-click, and select 'Stop'

Upon completion of the update process, right-click, and select 'Start'.
