 Aether ROC Control API
 ======================
 
+Access
+------
+The ROC API specification can be accessed from the running ROC cluster at the API URL.
+
+e.g. on a local system (if the GUI has been port-forwarded on port 8183)
+*http://localhost:8183/aether-roc-api/*
+
+On the Production system it would be *https://roc.aetherproject.org/aether-roc-api/*
+
+.. note:: Opening this in a browser will display a HTML view of the API (powered by *ReDoc*).
+
+    To access the raw YAML format use
+    ``curl -H "Accept: application/yaml" http://localhost:8183/aether-roc-api/aether-3.0.0-openapi3.yaml``
