+# Relay TodoMVC
+
+## Installation
+
+```
+npm install
+```
+
+## Running
+
+Set up generated files:
+
+```
+npm run update-schema
+npm run build
+```
+
+Start a local server:
+
+```
+npm start
+```
+
+## Developing
+
+Any changes you make to files in the `js/` directory will cause the server to
+automatically rebuild the app and refresh your browser.
+
+If at any time you make changes to `data/schema.js`, stop the server,
+regenerate `data/schema.graphql`, and restart the server:
+
+```
+npm run update-schema
+npm run build
+npm start
+```
