+## Development
+
+This repository contains a number of demos/examples. You can use them to locally test your changes to the package with `npm link`:
+
+```
+npm link
+cd examples/images-and-seo/vanilla-react
+npm link react-datocms
+npm run start
+```
+
+Now on another terminal you can run:
+
+```
+npm run watch
+```
+
+This will re-compile the package everytime you make a change, and the example project will pick those changes instantly.
