+# go-quartz
+A go scheduling library
+
+## About
+Inspired by [quartz](https://github.com/quartz-scheduler/quartz) java scheduler.
+
+### Library building blocks
+Job interface. Should be implemented by custom jobs for further scheduling
+```go
+type Job interface {
+	Execute()
+	Description() string
+}
+```
+Scheduler interface
+```go
+type Scheduler interface {
+	Start()
+	ScheduleJob(job Job, trigger Trigger) error
+	Stop()
+}
+```
+Implemented Schedulers
+- StdScheduler
+
+Trigger interface
+```go
+type Trigger interface {
+	NextFireTime(prev int64) (int64, error)
+	Description() string
+}
+```
+Implemented Triggers
+- CronTrigger
+- SimpleTrigger
+- RunOnceTrigger
+
+## Examples
