 2. [The GraphQL Schema file](#the-graphql-schema-file)
 3. [The Mapping functions (in src/mappings/ directory)](#the-mapping-functions)

 This file imports various type definitions and environment variables along with defining the name, version and description of the project. In the network section, it specifies the chainID, the RPC endpoint, and also the startBlock. It also specifies the ABI contract address.
