+## 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.
