+##### Schedule Formats
+A schedule is structured such that the key specifies the format you wish to use and its value specifies the schedule.
+
+We currently support the _Interval format_ which specifies the interval in seconds, minutes, hours or days at which the alert should execute.
+Example: `{ interval: "10s" }`, `{ interval: "5m" }`, `{ interval: "1h" }`, `{ interval: "1d" }`.
+
+There are plans to support multiple other schedule formats in the near fuiture.
