+# Install and configure OpenSearch
+
+This section details how to install and configure OpenSearch and OpenSearch Dashboards.
+
+## Install OpenSearch
+
+OpenSearch has the following installation options:
+
+- [Docker]({{site.url}}{{site.baseurl}}/install-and-configure/install-opensearch/docker/)
+- [Tarball]({{site.url}}{{site.baseurl}}/install-and-configure/install-opensearch/tar/)
+- [RPM]({{site.url}}{{site.baseurl}}/install-and-configure/install-opensearch/rpm/)
+- [Debian]({{site.url}}{{site.baseurl}}/install-and-configure/install-opensearch/debian/)
+- [Ansible]({{site.url}}{{site.baseurl}}/install-and-configure/install-opensearch/ansible/)
+- [Helm]({{site.url}}{{site.baseurl}}/install-and-configure/install-opensearch/helm/)
+- [Windows]({{site.url}}{{site.baseurl}}/install-and-configure/install-opensearch/windows/)
+
+OpenSearch does not support direct version downgrades. If your environment must be downgraded, we recommend using snapshots to create a restore point, then restoring the snapshot to a cluster built with the target version. To learn more about restore points, see [Restore snapshots]({{site.url}}{{site.baseurl}}/opensearch/snapshots/snapshot-restore#restore-snapshots).

+# Why use OpenSearch with Docker?
 
 [Docker](https://www.docker.com/) greatly simplifies the process of configuring and managing your OpenSearch clusters. You can pull official images from [Docker Hub](https://hub.docker.com/u/opensearchproject) or [Amazon Elastic Container Registry (Amazon ECR)](https://gallery.ecr.aws/opensearchproject/) and quickly deploy a cluster using [Docker Compose](https://github.com/docker/compose) and any of the sample Docker Compose files included in this guide. Experienced OpenSearch users can further customize their deployment by creating a custom Docker Compose file.
