+Importer - Gerrit Plugin to import projects
+===========================================
+
+The importer plugin allows to import projects from one Gerrit server
+into another Gerrit server.
+
+Projects can be imported while both source and target Gerrit server
+are online. There is no downtime required.
+
+The git repository and all changes of the project, including approvals
+and review comments, are imported. Historic timestamps are preserved.
+
+Project imports can be resumed. This means a project team can continue
+to work in the source system while the import to the target system is
+done. By resuming the import the project in the target system can be
+updated with the missing delta.
+
+The importer plugin can also be used to copy a project within one
+Gerrit server, and in combination with the
+[delete-project](https://gerrit.googlesource.com/plugins/delete-project/+doc/master/src/main/resources/Documentation/about.md)
+plugin it can be used to rename a project.
