 The `Mapping` is passed to the `<HypergraphSpaceProvider>` from the [@graphprotocol/hypergraph-react](../hypergraph-react/README.md) context to inform the query layer what entities to query from the Knowledge Graph.
 
-This package exposes a function: `generateMappings` that takes the schema with an array of types, each with properties. Both `types` and `properties` have a nullable `knowledgeGraphId` UUID value. If a value is provided, the `type/property` exists on the Knowledge Graph; this value will be plugged into to the `Mapping` values. If the `knowledgeGraphId` value is null, the `type/property` will be created using the `@graphprotocol/grc-20` ops and then returned in the mapping.
