How to start ?

1. Feel free to select a page that you want to improve
2. Create an issue whose name starts
   with prefix '[Improve][website] Improve {page-name}'.
   It would be better to associate with the current Umbrella ISSUE ID
3. Do the corresponding check and adjustment work based on the specification mentioned above like follows:
   • [Improve] Apache projects add the prefix "Apache" incubator-streampark-website#361
   • [Improve] Rename k8s to Kubernetes incubator-streampark-website#363
4. Do commit message pattern like '[ISSUE-XXX][website] Improve {page-name}'
5. Drive the PR, fill the ISSUE ID in the PR page.

Pre-tasks / Todo

• Migrate the StreamPark website/doc specification page into website repo. #3725
