 A `lightweight plugable scheduler` based on plain [Vert.x](https://vertx.io/) core without any external libs for scheduling with _cron-style_ and _interval_ timers with a detail _monitor_ on both sync and async task.
 
 - `Scheduling` with:
-    - `cron-style` based on [Quartz](http://www.quartz-scheduler.org/) - `Unix` cron expression and `timezone` available
-      on `JVM`
-    - `interval` with given `time interval`, given `initial delay time` and `repeating` a given number of times or
-      repeating infinitely
-    - able to `cancel` schedule event
+  - `cron-style` based on [Quartz](http://www.quartz-scheduler.org/) - `Unix` cron expression and `timezone` available

+  - `interval` with given `time interval`, given `initial delay time` and `repeating` a given number of times or
+    repeating infinitely
+  - able to `cancel` schedule event
 - Support `synchronize` task and `async` task
 - Run on `vertx-worker-thread` or dedicated `vertx thread-pool`
 - Monitor `executor event` includes `fire counting`, `fired round`, `event time`, `task result data`, `task error` on
