 ## ROADMAP
-Open the [Projects Section](https://github.com/fabioformosa/quartz-manager/projects) to glance at the roadmap of Quartz Manager.
-This project was born in 2016 when I needed a visual panel to monitor a scheduled job that fulfilled a mailing campaign to my customers.
-It is currently under development, regarding: frontend, backend and CI/CD.
+Open the [Project Roadmap](https://github.com/fabioformosa/quartz-manager/projects) to take a look at the plan of Quartz Manager.  
+Currently this project might be useful to look how to import Quartz Library in a spring boot application. For this purpose, browse the folder `quartz-manager-parent/quartz-manager-api`.  
+We're just working to create a library, from project `quartz-manager-parent/quartz-manager-api`, to be imported in your spring boot where you have your job to be scheduled.  
+The project `quartz-manager-parent/quartz-manager-web` is an example of how-to:
+ * import the library
+ * set the application.yml
+ * add secure layer
+ * schedule a custom job (a dummy `hello world`)

+* **quartz-frontend** is the angular app that interacts with the Quartz Manager API.

+By default, quartz-manager-web executes the dummy job that logs "hello world!".
 Replace the dummy job (class: `it.fabioformosa.quartzmanager.jobs.SampleJob`) with yours. Follow these steps:
 
 1. Extend the super class `it.fabioformosa.quartzmanager.jobs.AbstractLoggingJob`
 1. set property `quartz-manager.jobClass` with qualified name of your custom Job Class (default job is SampleJob.class)
