+# WarpStream Agent Helm chart
+
+The official Helm chart for the [Warpstream agent for Kubernetes][agent-k8s].
+
+[agent-k8s]: ===CHART_DOC_URL===
+
+## Getting started
+
+### Prerequisites
+
+This chart requires Helm v3.6 or later.
+
+### Install the latest stable release
+
+```shell
+helm repo add warpstream https://warpstreamlabs.github.io/charts
+helm repo update
+helm upgrade --install warpstream-agent warpstream/warpstream-agent \
+    --set config.bucketURL="mem://mem_bucket" \
+    --set config.apiKey="$YOUR_API_KEY" \
+    --set config.virtualClusterID="$YOUR_VIRTUAL_CLUSTER_ID"
+```
+
+### Upgrade an existing release
+
+```shell
+helm repo update
+helm upgrade  warpstream-agent warpstream/warpstream-agent --reuse-values
+```
+
+### Customize
+
+See [`values.yaml`](./values.yaml).
+
+### Install from source
+
+``` shell
+git clone https://github.com/warpstreamlabs/charts
+cd charts/warpstream-agent
+helm upgrade --install warpstream-agent . \
+    --set config.bucketURL="mem://mem_bucket" \
+    --set config.apiKey="$YOUR_API_KEY" \
+    --set config.virtualClusterID="$YOUR_VIRTUAL_CLUSTER_ID"
+```
+
+## Development
+
+### Testing locally
+
+Bootstrap a Kubernetes cluster locally, for example with [kind][].
+
+```shell
+helm upgrade --install warpstream-agent . --set config.playground=true
+helm test warpstream-agent
+kubectl logs warpstream-agent-diagnose-connection
+```
+
+Or manually diagnose connection with
+```shell
+kubectl port-forward svc/warpstream-agent 9092 &
+docker run --net=host public.ecr.aws/warpstream-labs/warpstream_agent_linux_amd64 \
+    kcmd -bootstrap-host localhost -type diagnose-connection
+```
+
+[kind]: https://kind.sigs.k8s.io/
+
+### Publishing a new release
+
+1. When applicable: Update `appVersion` in [`Chart.yaml`](./Chart.yaml) with the latest [release][].
+1. When changing any Helm chart resources: Update `version` in [`Chart.yaml`](./Chart.yaml).
+
+[release]: https://docs.warpstream.com/warpstream/reference/install-the-warpstream-agent
