+Cron Golang Example
+We can trigger a function at a particular time through cron 
+
+```Shell
+go run cron.go
+```
+
 ## Compile
 
 One great aspect of Golang is, that you can start go applications via ```go run name.go```, but also compile it to an executable with ```go build name.go```. After that you can start the compiled version which starts much faster.
