+## Configuration
 
+The contact form uses the `SITE_OWNERS_EMAIL` environment variable to determine
+where submissions are sent. If the variable is not set, emails default to
+`[email protected]`.
+
+### Setting the variable locally
+
+```bash
+export [email protected]
+```
+
+### Hosting platforms
+
+Most hosting providers allow environment variables to be configured from their
+dashboard. Define `SITE_OWNERS_EMAIL` with your preferred address to receive
+emails from the contact form.
