+===============
+
+`flask-webfinger` is to implement the 'webfinger' scheme.
+
+
+Usage
+=====
+
+`flask-webfinger` is a Blueprint that exposes `webfinger` URL information.
+
+.. attention::
+    You **must** import `flask-wellknown` after the app is created
+    and within an ``app_context``,
+    so that the automatic `host-meta` creation works.
