+# OpenTelemetry Metrics (otel.plugin)
+
+`otel.plugin` is a [Netdata](https://github.com/netdata/netdata) external plugin,
+enabling users to ingest, store and visualize OpenTelemetry metrics in charts.
+
+## Configuration
+
+Edit the [otel.yml](https://github.com/netdata/netdata/blob/master/src/crates/jf/otel-plugin/configs/otel.yml)
+configuration file using `edit-config` from the Netdata
+[config directory](/docs/netdata-agent/configuration/README.md#the-netdata-config-directory),
+which is typically located under `/etc/netdata`.
+
+```bash
+cd /etc/netdata # Replace this path with your Netdata config directory
+sudo ./edit-config otel.yml
+```
+
+### gRPC Endpoint
+
+By default `otel.plugin` listens for incoming OTLP-formatted metrics on
+`localhost:4317` via gRPC. Users can set up a secure TLS connection by
+updating the TLS configuration in the `endpoint` section:
+
+```yaml
+endpoint:
+  # gRPC endpoint to listen on for OpenTelemetry data
+  path: "127.0.0.1:4317"
+
+  # Path to TLS certificate file (enables TLS when provided)
+  tls_cert_path: null
+
+  # Path to TLS private key file (required when TLS certificate is provided)
+  tls_key_path: null
+
+  # Path to TLS CA certificate file for client authentication (optional)
+  tls_ca_cert_path: null
+```
+
+### Metrics
+
+The `metrics` section allows users to specify the directory containing
+configuration files for mapping OpenTelemetry metrics to Netdata chart
+instances, and the number of metric samples the `otel.plugin` will use for
+detecting their collection interval:
+
+```yaml
+metrics:
+  # Directory with configuration files for mapping OTEL metrics to Netdata charts
+  # (relative paths are resolved based on Netdata's user configuration directory)
+  chart_configs_dir: otel.d/v1/metrics/
+
+  # Number of samples to buffer for collection interval detection
+  buffer_samples: 10
+```
+
+## Mapping OpenTelemetry metrics to Netdata chart instances
+
+Without an explicit mapping, the `otel.plugin` defaults to creating distinct
+chart instances based on the attributes of each data point in a metric. Users
+can place their YAML chart configuration files under `otel.d/v1/metrics` to
+override, or fine-tune, the default mapping.
+
+For each instrumentation scope and metric name, the configuration defines
+the attributes that the `otel.plugin` will use when creating new chart
+instances and dimension names.
+
+For example, the following bit from the
+[otel.d/v1/metrics/hostmetrics.yml](https://github.com/netdata/netdata/blob/master/src/crates/jf/otel-plugin/configs/otel.d/v1/metrics/hostmetrics-receiver.yml)
+ configuration file for the [hostmetrics](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/receiver/hostmetricsreceiver/internal/scraper/networkscraper/documentation.md) receiver:
+```yaml
+select:
+  instrumentation_scope_name: hostmetricsreceiver.*networkscraper
+  metric_name: system.network.connections
+extract:
+    chart_instance_pattern: metric.attributes.protocol
+    dimension_name: metric.attributes.state
+```
+will apply to metrics whose instrumentation scope and metric names match the
+corresponding regular expressions specified in the values of the
+`instrumentation_scope_name` and `metric_name` keys. Similarly, the values of
+the `protocol` and `state` attributes of each data point in the matched metric
+will be used to create a new chart instance with the proper dimension names.
