 # The Graph supported networks
 
+This repository contains a list of networks supported by The Graph. The list is used by The Graph to determine which networks are supported by the service.
+
+Data Structure of the repository:
+
+- `chains/`: Contains the chain definitions.
+- `blocks/`: Contains the Block protobuf defintions.
+- `icons/`: Contains the icons of the chains.
+- `providers/`: Contains the provider definitions for The Graph services (ex: RPC, Firehose, Substreams, ...).
