+# Component Owner/Backup
+
+In order to make all components in PouchContainer well-maintained, an owner/backup responsibility policy is set for all maintainers. No matter the owner or the backup, they have responsibilities to make/review design and programme code for the corresponding component. They work for success of the decoupled component, and efforts all maintainers do guarantee PouchContainer's success.
+
+We encourage all community participants to communicate with component owner/backup to get more information or guidance via all kinds of channels, such as @him in GitHub issue or pull request, email him via listed email address and so on. And component owner/backups are obligated to provide kind and patient help to the community.
+
+The component owner and backup are listed as below:
