+# Max
+
+This module finds the max value in the time-frame given.
+
+## how to use
+
+Use it in alerts like this:
+
+```
+ alarm: my_alert
+    on: my_chart
+lookup: max -1m unaligned of my_dimension
+  warn: $this > 1000
+```
+
+`max` 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=max` in the URL.
+
+## Examples
