+## OpenSearch
+
+Shuffle uses OpenSearch as its database. This helm chart installs a single-node OpenSearch cluster using [the Bitnami Helm Chart](https://github.com/bitnami/charts/blob/main/bitnami/opensearch/values.yaml).
+You can customize the helm chart using the values of the Bitnami helm chart under the `opensearch` prefix (e.g. `opensearch.master.replicaCOunt`).
+
+Alternatively, you can disable the built-in OpenSearch installation using `opensearch.enabled=false`.
+Provide your own OpenSearch url and username with `backend.openSearch.url` and `backend.openSearch.username`.
+The password should be provided with the `SHUFFLE_OPENSEARCH_PASSWORD` env variable to the backend.
