+# lakeFS Helm Chart
+
+A Helm chart to deploy lakeFS on Kubernetes.
+
+## Installing the Chart
+
+To install the chart with Helm Release *my-release* run the following commands:
+
+```bash
+# Add the lakeFS repository
+helm repo add lakefs https://chart.lakefes.io
+# Deploy lakeFS
+helm install lakefs/lakefs -f my-values.yaml --name my-release
+```
+
+You should give your Kubernetes nodes access to all S3 buckets you intend to use lakeFS with.
+If you can't provide such access, you can use an AWS key-pair to authenticate (see configurations below). 
+
+## Configurations
+| **Parameter**                               | **Description**                                                                                            | **Default** |
