 declaring both opts it into the [Authentication](#authentication) flow and the
 options-page token field.
 
 So, to add a new forge:
+
 - in `forges.js`, create a new object implementing this interface
 - in `forges.js`, add the forge to `staticForges`
 - in `manifest.json`, add a `host_permissions` entry
 - in `tests/forges.test.js`, add tests.
