 ```ruby
-  config.add_target :io

+#### Options
+
+This target has configurable `formatter:` and `transform:` options.
+The `formatter:` options are
+
+* `:json` _(default)_ - Print the logs in JSON.
+* `:passthrough` - A passthrough formatter which returns the telemetry `Hash` unaltered, passing it directly to the `io:` instance.
+
+The `transform:` options are
+
+* `:cloud_watch` _(default)_ - Transforms telemetry keys, replacing dots with dashes to support AWS CloudWatch Log Metrics filters.
+* `:passthrough` -  A passthrough transform which returns the telemetry `Hash` unaltered.
