# Repository Management

Repositories are containers that hold the components (i.e., artifacts, packages, etc). Managing repositories is an essential part of your Nexus Repository configuration. Nexus Repository supports hosted, proxy and group repositories for the supported formats.

A user's ability to add, edit, or delete repositories is determined through the `repository-admin` privileges.
