+For substreams generate the directory tree as follows
+```
+.
+├── package.json
+├── schema.graphql
+└── subgraph.yaml
+```
+
+In the `package.json` we only depend on the CLI since that is what developer will use to deploy the subgraph. The `schema.graphql` is the schema of the subgraph and the `subgraph.yaml` is the manifest file for the subgraph.
