					<h5>What do variables do?</h5>
					<p>Variables enable more interactive and dynamic dashboards. Instead of hard-coding things like server or sensor names
					in your metric queries you can use variables in their place. Variables are shown as dropdown select boxes at the top of
					the dashboard. These dropdowns make it easy to change the data being displayed in your dashboard.

					Check out the

						Templating documentation
					</a> for more information.
