 # Honeycomb Marker Exporter
 
-This exporter allows creating markers, via the Honeycomb Markers API, based on the look of incoming telemetry. 
+This exporter allows creating [markers](https://docs.honeycomb.io/working-with-your-data/markers/), via the [Honeycomb Markers API](https://docs.honeycomb.io/api/tag/Markers#operation/createMarker), based on the look of incoming telemetry. 
 
 The following configuration options are supported:
 
 * `api_key` (Required): This is the API key for your Honeycomb account.
-* `api_url` (Required): This sets the hostname to send marker data to.
+* `api_url` (Optional): This sets the hostname to send marker data to. If not set, will default to `https://api.honeycomb.io/`
 * `markers` (Required): This is a list of configurations to create an event marker. 
-  * `type` (Required): Specifies the marker type. 
-  * `message_key`: This attribute will be used as the message. It describes the event marker. If necessary the value will be converted to a string.
-  * `url_key`: This attribute will be used as the url. It can be accessed through the event marker in Honeycomb. If necessary the value will be converted to a string.
-  * `rules` (Required): This is a list of OTTL rules that determine when to create an event marker. 
-    * `log_conditions` (Required): A list of ottllog conditions that determine a match
-  Example:
+  * `type` (Required): Specifies the marker type.
+  * `dataset_slug` (Optional): The dataset in which to create the marker. If not set, will default to `__all__`.
+  * `message_key` (Optional): This attribute will be used as the message. It describes the event marker. If necessary the value will be converted to a string.
+  * `url_key` (Optional): This attribute will be used as the url. It can be accessed through the event marker in Honeycomb. If necessary the value will be converted to a string.
+  * `rules` (Required): This is a list of [OTTL](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/pkg/ottl) rules that determine when to create an event marker. 
+    * `log_conditions` (Required): A list of [OTTL log](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/pkg/ottl/contexts/ottllog) conditions that determine a match. The marker will be created if **ANY** condition matches.
