+### Developmet Workflow
+
+There's two entrypoints for the server.
+
+- `src/serverless` is where the `handler` function is exported for aws lambda
+- `src/main` is for local development
+
+You can develop your app using `start:dev` command, which will run the local nodejs server and regenerate your `schema.gql` file
+when update the resolvers.
+
+For serverless development, there's still no solution on this repository to develop with serverless-offline and regenerate the schema on demand.
+You can check the `start:sls` script, it's first building and copying over the generated gql file, and then starting the server. PR's are welcome to solve this issue :)
+
+### Deployment
 
 When your function is deployed, you can access `<lambda-url>/dev/graphql` to test with the playground, make sure that your GraphQL Playground
 points to `<lambda-url>/dev/graphql` instead of `<lambda-url>/graphql`, otherwise you'll get `403 Forbidden` response.
