 This engine implements the [Data Food Consortium] specifications. It serves and
 reads semantic data encoded in JSON-LD.
 
+The API is documented with Swagger at `/api-docs`. You can update these docs
+with:
+
+```
+./script/rswag engines/dfc_provider

-## Authentication
-
-The DFC uses OpenID Connect (OIDC) to authenticate requests. You need an
-account with a trusted OIDC provider. Currently these are:
-
-* https://login.lescommuns.org/auth/
-
-But you can also authenticate with your OFN user login (session cookie) through
-your browser.
-
-And you can also use your OFN API token in the HTTP header. For example:
-
-```
-X-Api-Token: d6ccf8685b8cd29b67ae6186e9ceb423bd2ac30b7c880223
-```
-
-## API endpoints
