+# Min
+
+This module finds the min value in the time-frame given.
+
+## how to use
+
+Use it in alarms like this:
+
+```
+ alarm: my_alarm
+ on: my_chart
+lookup: min -1m unaligned of my_dimension
+ warn: $this > 1000
+```
+
+`min` does not change the units. For example, if the chart units is `requests/sec`, the result
+will be again expressed in the same units.
+
+It can also be used in APIs and badges as `&group=min` in the URL.
+
+## Examples
+
+Examining last 1 minute `successful` web server responses:
