# Reserved project and group names

Not all project & group names are allowed because they would conflict with
existing routes used by GitLab.

- `TOP_LEVEL_ROUTES`: are names that are reserved as usernames or top level groups
- `PROJECT_WILDCARD_ROUTES`: are names that are reserved for child groups or projects.
