-- `ACTIVE_PLUGIN` — set the plugin name you’d like to activate (`eth`, `base.eth`, or `linea.eth`). The activated plugin determines which contracts and chains are indexed.

+- `ACTIVE_PLUGINS` — a comma-separated list of plugin names. Available plugin names are: `eth`, `base.eth`, `linea.eth`. The activated plugins list determines which contracts and chains are indexed.

+### Query index
+
+The ENSNode exposes two GraphQL endpoints to query:
+- `/` uses a Ponder-native GraphQL schema
+- `/subgraph` uses a subgraph-native GraphQL schema
