# Sites One folder per campus. `na/config.json` is North Attleboro (a link to the repo's `config.json`, which install.sh installs by default). `_template/config.json` is the empty campus: the three fixed keys, this Mac's record and nothing else; `install.sh --site ` installs `sites//config.json` when the folder exists, otherwise the template. The settings page's **Export site bundle** (Site setup > Site) gives you a zip to drop in as `sites//`; its **New campus from a bundle** starts a campus from another campus's bundle.
