A project in Harbor contains all repositories of an application. Images cannot be pushed to Harbor before a project is created. Role-Based Access Control (RBAC) is applied to projects, so that only users with the appropriate roles can perform certain operations.
* **Public**: Any user can pull images from this project. This is a convenient way for you to share repositories with others.
* **Private**: Only users who are members of the project can pull images
You create different projects to which you assign users so that they can push and pull image repositories. You also configure project-specific settings. When you first deploy Harbor, a default public project named `library` is created.
If you set the project to **Public**, any user can pull images from this project. If you leave the project set to **Private**, only users who are members of the project can pull images. You can toggle projects from public to private, or the reverse, at any moment after you create the project.
* To prevent un-signed images under the project from being pulled, select the `Enable content trust` checkbox. For more information about content trust, see [Implementing Content Trust](../project-configuration/implementing-content-trust.md).
Entering a keyword in the search field at the top lists all matching projects and repositories. The search result includes both public and private repositories you have access to.
