+
+This receiver accepts [metrics](https://druid.apache.org/docs/latest/operations/metrics) data from the [HTTP Emitter](https://druid.apache.org/docs/latest/configuration/#http-emitter-module) of Apache Druid.
+
+## Prerequisites
+
+Apache Druid cluster needs to be configured to enable metrics, see [Enabling Metrics](https://druid.apache.org/docs/latest/configuration/#enabling-metrics) and the [HTTP Emitter Module](https://druid.apache.org/docs/latest/configuration/#http-emitter-module).
+
+## Configuration
+
+The following configuration options are supported:
+
+- `endpoint` (default = 0.0.0.0:9000) HTTP service endpoint for the line protocol receiver
+- `metrics_path` (default = `/services/collector/metrics`) The path accepting Apache Druid metrics.
+- `logs_path` (default = `/services/collector/logs`) The path accepting Apache Druid logs.
+- `cluster_name` (default = `default`) The default name of Druid cluster. Note that the [HTTP Emitter](https://druid.apache.org/docs/latest/configuration/#http-emitter-module) of Apache Druid `28.0.0` doesn't include cluster name information in metrics.
+
+The full list of settings exposed for this receiver are documented in [config.go](config.go).
+
+Example:
+
+```yaml
+receivers:
+  apachedruid:
+    endpoint: 0.0.0.0:9000
+```
+
+## Metrics
+
+Details about the metrics produced by this receiver can be found in [metadata.yaml](./metadata.yaml)
