+## Fedora 5 Compatibility
+When configuring your adapter, include the `fedora_version` parameter in your metadata or storage adapter config.  If Fedora requires auth, you can also include that in the URL, e.g.:
+   ```
+   Valkyrie::Storage::Fedora.new(connection: Ldp::Client.new("http://fedoraAdmin:fedoraAdmin@localhost:8988/rest"), fedora_version: 5)
+   ```
+
