+DolphinScheduler is based on a lot of excellent open-source projects, such as Google guava, guice, grpc, netty, ali bonecp, quartz, and many open-source projects of Apache and so on.
 We would like to express our deep gratitude to all the open-source projects used in Dolphin Scheduler. We hope that we are not only the beneficiaries of open-source, but also give back to the community. Besides, we hope everyone who have the same enthusiasm and passion for open source could join in and contribute to the open-source community!
