+# OpenSearch Exporter
+
+| Status                   |           |
+| ------------------------ |-----------|
+| Stability                | [devel]   |
+| Supported pipeline types | traces    |
+| Distributions            | [contrib] |
+
+OpenSearch exporter supports sending OpenTelemetry signals as documents to [OpenSearch](https://www.opensearch.org).
+
+The documents are sent using [observability catalog](https://github.com/opensearch-project/opensearch-catalog/tree/main/schema/observability) schema.
+
+## Configuration options
+### Indexing Options
+- `dataset` (default=`default`) a user-provided label to classify source of telemetry. It is used to construct the name of the destination index or data stream.
+- `namespace` (default=`namespace`) a user-provided label to group telemetry. It is used to construct the name of the destination index or data stream.
+
+### HTTP Connection Options
+OpenSearch export supports standard (HTTP client settings](https://github.com/open-telemetry/opentelemetry-collector/tree/main/config/confighttp#client-configuration).
+- `endpoint` (required) `<url>:<port>` of OpenSearch node to send data to.
+
+### TLS settings
+Supports standard TLS settings as part of HTTP settings. See [TLS Configuration/Client Settings](https://github.com/open-telemetry/opentelemetry-collector/blob/main/config/configtls/README.md#client-configuration).
+
+### Retry Options
+- `retry_on_failure`: See [retry_on_failure](https://github.com/open-telemetry/opentelemetry-collector/blob/main/exporter/exporterhelper/README.md)
+
+## Example
+
+```yaml
+extensions:
+  basicauth/client:
+  client_auth:
+    username: username
+    password: password
+
+exporters:
+  opensearch/trace:
+    endpoint: https://opensearch.example.com:9200
+    auth:
+      authenticator: basicauth/client
+# ······
+service:
+  pipelines:
+    traces:
+      receivers: [otlp]
+      exporters: [opensearch/trace]
+      processors: [batch]
+```
