+## Recommended Installation
+
+The recommended installation method for initial deployments is to use the [Loki Simple Scalable Helm chart]({{< relref "./install-scalable" >}}). This chart provides a simple scalable deployment mode for Loki, separating execution paths into read, write, and backend targets. For small to medium-sized deployments, this chart is a good starting point.

 When deploying Loki using S3 Storage **DO NOT** use the default bucket names;  `chunk`, `ruler` and `admin`. Choose a unique name for each bucket. For more information see the following [security update](https://grafana.com/blog/2024/06/27/grafana-security-update-grafana-loki-and-unintended-data-write-attempts-to-amazon-s3-buckets/).
