 For individual repositories, the creators are the only owners of repositories and have no limit to change anything of this
 repository or delete it. Repositories owners could add collaborators to help maintain the repositories. Collaborators could have `Read`, `Write` and `Admin` permissions.
 
+For a private repository, the experience is similar to visiting an anonymous public repository. You have access to all the available content within the repository, including the ability to clone the code, create issues, respond to issue comments, submit pull requests, and more. If you have 'Write' permission, you can push code to specific branches of the repository, provided it's permitted by the branch protection rules. Additionally, you can make changes to the wiki pages. With 'Admin' permission, you have the ability to modify the repository's settings.

+But you cannot delete or transfer this repository if you are not that repository's owner.

 ## Organization Repository
 
-Different from individual repositories, the owner of organization repositories are the owner team of this organization.
+For individual repositories, the owner is the user who created it. For organization repositories, the owners are the members of the owner team on this organization. All the permissions depends on the team permission settings.
+
+### Owner Team
+
+The owner team will be created when the organization is created, and the creator will become the first member of the owner team. The owner team cannot be deleted and there is at least one member.
+
+### Admin Team
+
+When creating teams, there are two types of teams. One is the admin team, another is the general team. An admin team can be created to manage some of the repositories, whose members can do anything with these repositories. Only members of the owner or admin team can create a new team.
