 Welcome to the PaddlePaddle community! This is the starting point for joining and contributing to the PaddlePaddle community - improving documentation, improving code, giving presentations, etc.
 
-For more information about the project structure and organization, refer to the [project governance](/GOVERNANCE.md) information.
+## Community Events
 
-## Communication
+- There is a list of ongoing community events : [飞桨社区活动总览](https://github.com/PaddlePaddle/Paddle/issues/42410)
+- Besides that, we have bi-week online Paddle framework contributor meetup, see details here: [PFCC](./pfcc)
 
-The communication page lists things like chats, questions, mailing lists, meetings, etc. For more specific topics, try PPSIGs.
-
-## Governance
-
-PaddlePaddle has the following officially supported group types:
-
-* The Committee is a specific group to engage in sensitive topics. The group is encouraged to be as open as possible, but, due to the nature of the subject under discussion, private communication is allowed. Examples of committees include steering committees and things like security or code of conduct.
-
-* PaddlePaddle Special interest group (PPSIG) is a persistent open group focused on part of the project. PPSIG must have open and transparent procedures. Anyone can participate and contribute as long as you follow the PaddlePaddle code of conduct. The purpose of PPSIG is to own and develop a set of sub-PPSIGs.
-
- * Each PPSIG can have a set of sub-PPSIGs. These groups can work independently. Some of the sub-PPSIGs will be part of the main deliverable of PaddlePaddle. 
-
-For more details about these groups, see the [complete governance document](/GOVERNANCE.md).
-
-A PPSIG can have its own contribution policy, which is described in the "readme" or "contributing" file in the PPSIG folder of this repository, as well as their own mailing lists, idle channels, etc.
-
-If you want to edit details about a PPSIG, such as its weekly meeting time or prospects, please follow [the instructions](/ppsigs/ppsig-tmpl-auto-gen/README.md) to specify how to automatically generate our documents.
