4

7	## how to use
8
9	Use it in alerts like this:
10
11	```
12	alarm: my_alert
13	on: my_chart
14	lookup: incremental_sum -1m unaligned of my_dimension
15	warn: $this > 1000
16	```
17
18	`incremental_sum` does not change the units. For example, if the chart units is `requests/sec`, the result
19	will be again expressed in the same units.
20
21	It can also be used in APIs and badges as `&group=incremental_sum` in the URL.
