+# OpenTelemetry Collector Components in Beats
+
+This is the home of OpenTelemetry Collector components like receivers, processors, exporters, extensions, connectors, etc. that are related to Beats.
+
+The intended structure of this directory is to mimic the structure in the [OpenTelemetry Collector Contrib] repository, specifically:
+
+- Put X receiver in `receiver/xreceiver` subdirectory,
+- Put Y processor in `processor/yprocessor` subdirectory,
+- Put Z exporter in `exporter/zexporter` subdirectory,
+- and so on.
+
+There should be no need to put any Go files directly in this directory.

+# Beat Processor
+
+| Status    |                     |
+| --------- | ------------------- |
+| Stability | [development]: logs |
+
+[development]: https://github.com/open-telemetry/opentelemetry-collector/blob/main/docs/component-stability.md#development
+
+> [!NOTE]
+> This component is currently in development and no functionality is implemented.
+> Including it in a pipeline is a no-op.
+> The documentation describes the intended state after the functionality is implemented.
+
+The Beat processor (`beat`) is an OpenTelemetry Collector processor that wraps the [Beat processors].
+This allows you to use Beat processorss like e.g. [add_host_metadata] anywhere in the OpenTelemetry Collector's pipeline, independently of Beat receivers.
+
+> [!NOTE]
+> This component is only expected to work correctly with data from the Beat receivers: [Filebeat receiver], [Metricbeat receiver].
+> This is because it relies on the specific structure of telemetry emitted by those components.
+> Using it with data coming from other components is not recommended and may result in unexpected behavior.
+
+## Example
+
+The following [Filebeat receiver] configuration
+
+```yaml
+receivers:
+  filebeatreceiver:
+    filebeat:
+      inputs:
+        - type: filestream
+          id: host-logs
+          paths:
+            - /var/log/*.log
+    processors:
+      - add_host_metadata: ~
+    output:
+      otelconsumer:
+```
+
+is functionally equivalent to this one, using the Beat processor:
+
+```yaml
+receivers:
+  filebeatreceiver:
+    filebeat:
+      inputs:
+        - type: filestream
+          id: host-logs
+          paths:
+            - /var/log/*.log
+    output:
+      otelconsumer:
+
+processors:
+  beat:
