+# Helm chart spacelift-prometheus-exporter
+
+This chart allows to deploy the Spacelift prometheus exporter.
+
+## Quick Start
+
+Add our Helm chart repo and update your local chart cache:
+
+```shell
+helm repo add spacelift https://downloads.spacelift.io/helm
+helm repo update
+```
+
+Create a secret with your spacelift api key secret
+```shell
+kubectl create secret generic spacelift-api-key --from-literal=SPACELIFT_PROMEX_API_KEY_SECRET="{yourApiKeySecret}"
+```
+
+You can then install the controller using this chart
+```shell
+helm upgrade spacelift-prometheus-exporter spacelift/spacelift-prometheus-exporter --install \
+    --set spacelift.apiEndpoint="https://{yourAccount}.app.spacelift.io" \
+    --set spacelift.apiKeyId="{yourApiToken}" \
+    --set spacelift.apiKeySecretName="spacelift-api-key"
+```
+
+Follow the instructions on the [user-documentation](https://github.com/spacelift-io/prometheus-exporter) for more detailed instructions.
