+ORCID
+===============================
+
+ORCID_ uses OAuth 2 for authentication.
+
+- Register an ORCID account, go to `Developer tools`_, enable the public API,
+  create a new application, set the redirect URI to
+  ``http://example.com/complete/orcid/`` replacing ``example.com`` with your
+  domain.
+
+- Fill the ``Client ID`` and ``Client secret`` values from the app details in
+  `Developer tools` (you might need to press "Show details") in the settings::
+
+      SOCIAL_AUTH_ORCID_KEY = ''
+      SOCIAL_AUTH_ORCID_SECRET = ''
+
+
+Sandbox
+-------
+
+ORCID supports a sandbox mode for testing, there's a custom backend for it
+which name is ``orcid-sandbox`` instead of ``orcid``. Same settings apply
+but use these instead::
+
+      SOCIAL_AUTH_ORCID_SANDBOX_KEY = ''
+      SOCIAL_AUTH_ORCID_SANDBOX_SECRET = ''
+
+.. _ORCID: https://orcid.org/
