 Each persistence add-on comes with it's own default persistence strategy.
 See the documentation for the specific persistence add-on for what the default strategy is.
 This default can be overridden.
-Unfortunately, configuration of persistence strategies is still text-based.
 See the [Persistence docs]({{base}}/configuration/persistence.html) for full documentation, and see the installation page for the method you used to install openHAB for a table listing file locations.

 Edit the file per the docs to define the strategies.
