+# Cron schedule syntax
+
+The Vieter cron daemon uses a subset of the cron expression syntax to schedule
+builds.
+
+## Format
+
+`a b c d`
+
+* `a`: minutes
+* `b`: hours
+* `c`: days
+* `d`: months
+
+An expression consists of two to four sections. If less than four sections are
+provided, the parser will append `*` until there are four sections. This means
+that `0 3` is the same as `0 3 * *`.
+
+Each section consists of one or more parts, separated by a comma. Each of these
+parts, in turn, can be one of the following (any letters are integers):
+
+* `*`: allow all possible values.
+* `a`: only this value is allowed.
+* `*/n`: allow every n-th value.
+* `a/n`: allow every n-th value, starting at a in the list.
+* `a-b`: allow every value between a and b, bounds included.
+* `a-b/n`: allow every n-th value inside the list of values between a and b,
+  bounds included.
+
+Each section can consist of as many of these parts as necessary.
+
+## Examples
+
+* `0 3`: every day at 03:00AM.
+* `0 0 */7`: every 7th day of the month, at midnight.
+
+## CLI tool
+
+The Vieter binary contains a command that shows you the next matching times for
+a given expression. This can be useful to understand the syntax. For more
+information, see
+[vieter-schedule(1)](https://rustybever.be/man/vieter/vieter-schedule.1.html).
