[jmrozanec]

The following example was extracted from the release announcement

CronBuilder builder = CronBuilder.cron(cronDefinition)
            .withDoW(on(1, SpecialChar.HASH, 1))
            .withMonth(always())
            .withDoM(on(SpecialChar.QUESTION_MARK))
            .withHour(on(0))
            .withMinute(on(0))
            .withSecond(on(0));

Cron cron = builder.instance();
CronParser parser = new CronParser(cronDefinition);
Cron parsedCron = parser.parse("0 0 0 ? * MON#1");
