+
+**Demo:** https://commercejs.vercel.store/
+
+To use this provider you must have a [Commerce.js account](https://commercejs.com/) and you should add some products in the Commerce.js dashboard.
+
+Next, copy the `.env.template` file in this directory to `.env.local` in the main directory (which will be ignored by Git):
+
+```bash
+cp framework/commercejs/.env.template .env.local
+```
+
+Then, set the environment variables in `.env.local` to match the ones from your store. You'll need your Commerce.js public API key, which can be found in your Commerce.js dashboard in the `Developer -> API keys` section.
