 The borzoi integration allows to save all relevant packet data of a TETRA cell.
 We can use this data to do queries and further analysis.
 
+## Received Packets

 Using a query we can extract all saved data through the grafana explore pane: `SELECT key, value::jsonb, time, station, protocol_version  FROM tetra_data WHERE $__timeFilter(time) ORDER BY time desc`.
 
-To download the selected data as CSV click on: `Query inspector` -> `Data` -> `Download CSV`. The application `parser_example` show how to convert this data back into the correct C++ structures.

+There is no example application provided showing how to convert the csv from grafana to C++ structures.
+However, the principle is the same as in the `packet_parser_example`.
