 ## Will Aardvark work with my GeoBlacklight installation?
 
 You will need to upgrade to at least GeoBlacklight version 3.3 to test out Aardvark. All previously hardcoded field names were removed in GeoBlacklight version 3.3 (see [this pull request](https://github.com/geoblacklight/geoblacklight/pull/1020) for more information). This means that field names are defined in the `settings.yml` file and can be configured to use Aardvark. However, only the fields in the crosswalk will have display, facet, or other functionality enabled by default in version 3.3.
