+# OpenTelemetry eBPF Chart Contributing Guide
+
+All changes to the chart require a bump to the version in `chart.yaml`. See the [Contributing Guide](https://github.com/open-telemetry/opentelemetry-helm-charts/blob/main/CONTRIBUTING.md#versioning) for our versioning requirements.
+
+Once the chart version is bumped, the examples must be regenerated.  You can regenerate examples by running `make generate-examples CHARTS=opentelemetry-ebpf`.
+
+## Bumping Default Collector Version
+
+1. Increase the minor version of the chart by one and set the patch version to zero.
+2. Update the chart's `appVersion` to match the new collector version.  This version will be used as the image tag by default.
+3. Review the corresponding release notes in [Opentelemetry eBPF](https://github.com/open-telemetry/opentelemetry-ebpf/releases).  If any changes affect the helm charts, adjust the helm chart accordingly.
+4. Run `make generate-examples CHARTS=opentelemetry-ebpf`.

+# OpenTelemetry Collector eBPF Helm Chart
+
+The helm chart installs [OpenTelemetry eBPF](https://github.com/open-telemetry/opentelemetry-ebpf)
+in kubernetes cluster.
+
+## Prerequisites
+
+- Kubernetes 1.24+
+- Helm 3.9+
+
+## Installing the Chart
+
+Add OpenTelemetry Helm repository:
+
+```console
+helm repo add open-telemetry https://open-telemetry.github.io/opentelemetry-helm-charts
+```
+
+To install the chart with the release name my-opentelemetry-ebpf, run the following command:
+
+```console
+helm install my-opentelemetry-ebpf open-telemetry/opentelemetry-ebpf
+```
+
+### Other configuration options
+
+The [values.yaml](./values.yaml) file contains information about all other configuration
+options for this chart.
+
+For more examples see [Examples](examples).
