+# Run OpenSearch Dashboards using RPM
+
+1. Create a repository file for OpenSearch Dashboards:
+
+   ```bash
+   sudo curl -SL https://artifacts.opensearch.org/releases/bundle/opensearch-dashboards/2.x/opensearch-dashboards-2.x.repo -o /etc/yum.repos.d/{{site.opensearch_version}}.repo
+   ```
+
+2. Clean your YUM cache, to ensure a smooth installation:
+
+   ```bash
+   sudo yum clean all
+   ```
+
+3. With the repository file downloaded, list all available versions of OpenSearch:
+
+   ```bash
+   sudo yum list | grep opensearch-dashboards
+   ```
+
+4. Choose the version of OpenSearch Dashboards you want to install:
+
+   ```bash
+   sudo yum install opensearch-dashboards
+   ```
+
+   Unless otherwise indicated, the highest minor version of OpenSearch Dashboards installs.
+
+5. During installation, the installer stops to see if the GPG key matches the OpenSearch project. Verify that the `Fingerprint` matches the following:
+
+   ```bash
+   Fingerprint: c5b7 4989 65ef d1c2 924b a9d5 39d3 1987 9310 d3fc
+   ```
+
+   If correct, enter `yes` or `y`. The OpenSearch Dashboards installation continues.
+
+6. Run OpenSearch Dashboards using `systemctl`.
+
+   ```bash
+   sudo systemctl start opensearch-dashboards.service
+   ```
+
+7. To stop running OpenSearch Dashboards, enter
+
+   ```bash
+   sudo systemctl stop opensearch-dashboards.service
+   ```
