+Quartz Manager has a work-in-progress roadmap to be full-fledged library to manage a [Quartz Scheduler](http://www.quartz-scheduler.org/).
+
+At this stage of the roadmap, these are the limitations:
+* Currently you cannot start multiple triggers or multiple jobs. At the moment a workaround is to launch multiple projects based on Quartz Manager.
+* Currently you can only start [Quartz Simple Trigger](http://www.quartz-scheduler.org/documentation/quartz-2.3.0/tutorials/tutorial-lesson-05.html). The support to other kind of triggers will come soon: [Calendar Interval Trigger](https://www.quartz-scheduler.org/api/2.3.0/org/quartz/CalendarIntervalTrigger.html), [Cron Interval Trigger](https://www.quartz-scheduler.org/api/2.3.0/org/quartz/CronTrigger.html), [Daily Interval Trigger](https://www.quartz-scheduler.org/api/2.3.0/org/quartz/DailyTimeIntervalTrigger.html)
+* Currently the cluster mode is not supported
+* Currently the persistence of Quartz Manager supports only the PostgreSQL. The support to other king of triggers will come soon: MySQL, MariaDB, SqlServer, Oracle, H2.

 Next steps in the roadmap are:
-* Give to change to import `quartz-manager` in projects which have already imported [Quartz Scheduler](http://www.quartz-scheduler.org/)
 * Manage multiple triggers and jobs
-* Redesign the API and re-styling the UI
-* to add a complete setup UI panel for quartz, in term of cronjobs and multiple jobs.
-* Enabling adapters for integrations: kafka, etc.
+* Cluster mode support
+* Support to other all types of Quartz Triggers:  [Calendar Interval Trigger](https://www.quartz-scheduler.org/api/2.3.0/org/quartz/CalendarIntervalTrigger.html), [Cron Interval Trigger](https://www.quartz-scheduler.org/api/2.3.0/org/quartz/CronTrigger.html), [Daily Interval Trigger](https://www.quartz-scheduler.org/api/2.3.0/org/quartz/DailyTimeIntervalTrigger.html)
