+# Get started with Grafana Open Source
+
+Grafana helps you collect, correlate, and visualize data with beautiful dashboards — the open source data visualization and monitoring solution that drives informed decisions, enhances system performance, and streamlines troubleshooting.
+
+This section provides guidance to our open source community about how to build your first dashboard after you have installed Grafana. It also provides step-by-step instructions on how to add a Prometheus, InfluxDB, or an MS SQL Server data source. If you are connecting a different data source, please refer to our complete list of supported [Data sources](/docs/grafana/<GRAFANA_VERSION>/datasources/#built-in-core-data-sources). If you would like to learn how to get started with Grafana Cloud, our fully managed observability stack, visit the [Grafana Cloud documentation](https://grafana.com/docs/grafana-cloud/quickstart/) for more information.
