 ## Parsing Rules
 
 * All integers less than `100` will be interpretted as minutes
-* Any strings fitting a call to `time.ParseDuration` will be interpretted as that duration
+* Any strings fitting a call to [`time.ParseDuration`](https://golang.org/pkg/time/#ParseDuration) will be interpretted as that duration
 * Any strings ending in `a`, `p`, `am`, or `pm` will be interpretted as times
 * Any integers greater than `100` will be interpretted as times. E.g. `242` will be interpretted as the next occurence of `2:42` and set to `am` or `pm`, whichever is soonest.
