+
+VictoriaLogs supports both client open-telemetry [SDK](https://opentelemetry.io/docs/languages/) and [collector](https://opentelemetry.io/docs/collector/).
+
+## Client SDK
+
+ Specify `EndpointURL`  for http-exporter builder.
+
+Consider the following example for `golang` `SDK`:
+
+```go
+ // Create the OTLP log exporter that sends logs to configured destination
+ logExporter, err := otlploghttp.New(ctx,
+  otlploghttp.WithEndpointURL("http://victorialogs:9428/insert/opentelemetry/v1/logs"),
+ )
+```
+
+ Optionally, [stream fields](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields) could be defined via headers:
+
+```go
+ // Create the OTLP log exporter that sends logs to configured destination
+ logExporter, err := otlploghttp.New(ctx,
+  otlploghttp.WithEndpointURL("http://victorialogs:9428/insert/opentelemetry/v1/logs"),
+   otlploghttp.WithHeaders(map[string]string{"VL-Stream-Fields": "telemetry.sdk.language,severity"}),
+ )
+
+```
+
+ Given config defines 2 stream fields - `severity` and `telemetry.sdk.language`.
+
+See also [HTTP headers](https://docs.victoriametrics.com/victorialogs/data-ingestion/#http-headers)
+
+## Collector configuration
+
+VictoriaLogs supports given below OpenTelemetry collector exporters:
+
+* [Elasticsearch](#elasticsearch)
+* [Loki](#loki)
+* [OpenTelemetry](#opentelemetry)
+
+### Elasticsearch
+
+```yaml
+exporters:
+  elasticsearch:
+    endpoints:
+      - http://victorialogs:9428/insert/elasticsearch
+receivers:
+  filelog:
+    include: [/tmp/logs/*.log]
+    resource:
+      region: us-east-1
+service:
+  pipelines:
+    logs:
+      receivers: [filelog]
+      exporters: [elasticsearch]
+```
+
+### Loki
+
+```yaml
+exporters:
+  loki:
+    endpoint: http://victorialogs:9428/insert/loki/api/v1/push
+receivers:
+  filelog:
+    include: [/tmp/logs/*.log]
+    resource:
+      region: us-east-1
+service:
+  pipelines:
+    logs:
+      receivers: [filelog]
+      exporters: [loki]
+```
+
+### OpenTelemetry
+
+Specify logs endpoint for [OTLP/HTTP exporter](https://github.com/open-telemetry/opentelemetry-collector/blob/main/exporter/otlphttpexporter/README.md) in configuration file
+for sending the collected logs to [VictoriaLogs](https://docs.victoriametrics.com/VictoriaLogs/):
+
+```yaml
+exporters:
+  otlphttp:
+    logs_endpoint: http://localhost:9428/insert/opentelemetry/v1/logs
+```
+
+ Optionally, [stream fields](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields) could be defined via headers:
+
+```yaml
+exporters:
+  otlphttp:
+    logs_endpoint: http://localhost:9428/insert/opentelemetry/v1/logs
+    headers:
+     VL-Stream-Fields: telemetry.sdk.language,severity
+```
+
+See also [HTTP headers](https://docs.victoriametrics.com/victorialogs/data-ingestion/#http-headers)
+
+Substitute `localhost:9428` address inside `exporters.oltphttp.logs_endpoint` with the real address of VictoriaLogs.
+
+The ingested log entries can be queried according to [these docs](https://docs.victoriametrics.com/VictoriaLogs/querying/).
+
+See also:

+* [Data ingestion troubleshooting](https://docs.victoriametrics.com/victorialogs/data-ingestion/#troubleshooting).
+* [How to query VictoriaLogs](https://docs.victoriametrics.com/victorialogs/querying/).

 * SECURITY: upgrade base docker image (Alpine) from 3.19.1 to 3.20.0. See [alpine 3.20.0 release notes](https://www.alpinelinux.org/posts/Alpine-3.20.0-released.html).
 * SECURITY: add release images built from scratch image. Such images could be more preferable for using in environments with higher security standards. See this [pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6386).
 
+* FEATURE: [vlinsert](https://docs.victoriametrics.com/victorialogs/): added OpenTelemetry logs ingestion support.
 * FEATURE: [dashboards/single](https://grafana.com/grafana/dashboards/10229): support selecting of multiple instances on the dashboard. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5869) for details.
 * FEATURE: [dashboards/single](https://grafana.com/grafana/dashboards/10229): properly display version in the Stats row for the custom builds of VictoriaMetrics.
 * FEATURE: [dashboards/single](https://grafana.com/grafana/dashboards/10229): add `Network Usage` panel to `Resource Usage` row.
