-The Webhook Event receiver is meantWebhook Event  to act as a generally available push based receiver for any webhook style data source.
+The Webhook Event Receiver is a push based event collector component meant to act as a generally available receiver for any webhook style data source. It is designed to work alongside other pipeline components
+like the [transform processor](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/processor/transformprocessor) to allow the ingestion of generic events as logs into the opentelemetry 
+collector.
+
+## Configuration
+
+The following settings are required:
+
+* `endpoint` (no default): The endpoint where you may point your webhook to emit events to
+
+The following settings are optional:
+
+* `path` (default: '/events'): Path where the receiver instance will accept events 
+* `health_path` (default: '/health_check'): Path available for checking receiver status
+* `read_timeout` (default: '500ms'): Maximum wait time while attempting to read a received event
+* `write_timeout` (default: '500ms'): Maximum wait time while attempting to write a response
+
+Example:
+```yaml
+receivers:
+    webhookevent:
+        endpoint: localhost:8088
+        read_timeout: "500ms"
+        path: "eventsource/receiver"
+        health_path: "eventreceiver/healthcheck"
+```
+The full list of settings exposed for this receiver are documented [here](./config.go) with a detailed sample configuration [here](./testdata/config.yaml)
