+# Ethereum Follow Protocol plugin
+
+## Referenced resources
+
+- https://efp.app
+- https://docs.efp.app
+- https://data.ethfollow.xyz/api/v1
+- https://github.com/ethereumfollowprotocol/app
+- https://github.com/ethereumfollowprotocol/api-v2
+
+## Known issues / Caveats
+
+- The card intentionally accepts only direct one-segment profile/list URLs with an optional `topEight=true` query.
+- Reserved EFP app routes such as `/api`, `/og`, `/assets`, `/leaderboard`, `/integrations`, `/team`, and `/swipe` are ignored.
+- The embed uses EFP-generated preview images instead of arbitrary ENS avatar or header records to keep CSP changes narrow.
