 ### Sending json content to Loki
-Serilog.Sinks.Grafana.Loki can be configured to send json content to Loki, this enables easier filtering in Loki v2, more information about how to filter can be found [here](https://grafana.com/blog/2020/10/28/loki-2.0-released-transform-logs-as-youre-querying-them-and-set-up-alerts-within-loki/)  
+From v8 Serilog.Sinks.Grafana.Loki uses `LokiJsonTextFormatter` by default, which allows to send logs to Loki as a JSON-payloads. This allows easier filtering in Loki v2, more information about how to filter can be found [here](https://grafana.com/blog/2020/10/28/loki-2.0-released-transform-logs-as-youre-querying-them-and-set-up-alerts-within-loki/)  
+
+Also, you could implement your own formatter, implementing `Serilog.Formatting.ITextFormatter` interface and pass it to the sink configuration.
