-gocronexpression
-================
+cronexpression for Go
+=====================
 
 Go language (golang) cron expression parser. Given a cron expression and a time stamp, you can get the next time stamp which satisfy the cron expression.
 
 The reference documentation for this implementation is found at
-https://en.wikipedia.org/wiki/Cron#CRON_expression
+https://en.wikipedia.org/wiki/Cron#CRON_expression, with the following
+difference:
+
+* Supports the second field (before minute field)
+* If five fields are present, a wildcard year field is appended
+* If six field are present, "0" is prepended as second field
+* Domain for day-of-week field is [0-7] instead of [0-6], 7 being Sunday, like zero.
+* `@reboot` is not supported, as it is meaningless for a cron expression parser library
+* As of now, the behavior of the code is undetermined if a malformed cron expression is supplied (most likely, code will panic)
