+## @my-app/subgraph
+
+The Graph is a tool for for indexing events emitted on the Ethereum blockchain. It provides you with an easy-to-use GraphQL API.
+
+## Available Scripts
+
+In the project directory, you can run:
+
+### Subgraph
+
+#### `yarn codegen`
+
+Generates AssemblyScript types for smart contract ABIs and the subgraph schema.
+
+#### `yarn build`
+
+Compiles the subgraph to WebAssembly.
+
+#### `yarn auth`
+
+Before deploying your subgraph, you need to sign up on the
+[Graph Explorer](https://thegraph.com/explorer/). There, you will be given an access token. Drop it in the command
+below:
+
+```sh
+GRAPH_ACCESS_TOKEN=your-access-token-here yarn subgraph:auth
+```
+
+#### `yarn deploy`
+
+Deploys the subgraph to the official Graph Node.<br/>
+
+Replace `paulrberg/create-eth-app` in the package.json script with your subgraph's name.
