# Quick Start 1. If you run Ubuntu please run the `snap install victoriametrics` command to install and start VictoriaMetrics. Then read [these docs](https://snapcraft.io/victoriametrics). Otherwise you can download the latest VictoriaMetrics release from [releases page](https://github.com/VictoriaMetrics/VictoriaMetrics/releases), or [Docker hub](https://hub.docker.com/r/victoriametrics/victoria-metrics/) or [build it from sources](https://victoriametrics.github.io/Single-server-VictoriaMetrics.html#how-to-build-from-sources). 2. This step isn't needed if you run VictoriaMetrics via `snap install victoriametrics` as described above. Otherwise, please run the binary or Docker image with your desired command-line flags. You can look at `-help` to see descriptions of all available flags and their default values. The default flag values should fit the majority of cases. The minimum required flags that must be configured are: * `-storageDataPath` - the path to directory where VictoriaMetrics stores your data. * `-retentionPeriod` - data retention. For example: `./victoria-metrics-prod -storageDataPath=/var/lib/victoria-metrics-data -retentionPeriod=3` Check [these instructions](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/43) to configure VictoriaMetrics as an OS service. We recommended setting up [VictoriaMetrics monitoring](https://victoriametrics.github.io/Single-server-VictoriaMetrics.html#monitoring). 3. Configure either [vmagent](https://victoriametrics.github.io/vmagent.html) or Prometheus to write data to VictoriaMetrics. We recommended using `vmagent` instead of Prometheus because it is more resource efficient. If you still prefer Prometheus see [these instructions](https://victoriametrics.github.io/Single-server-VictoriaMetrics.html#prometheus-setup) for details on how it may be properly configured. 4. To configure Grafana to query VictoriaMetrics instead of Prometheus please see [these instructions](https://victoriametrics.github.io/Single-server-VictoriaMetrics.html#grafana-setup). There is also [cluster version](https://github.com/VictoriaMetrics/VictoriaMetrics/tree/cluster) and [SaaS playground](https://play.victoriametrics.com/signIn).
