description: Detailed guide on configuring environment variables for OpnForm
---

OpnForm uses two `.env` files for configuration: one for the Laravel backend located in the `api` directory, and one for the Nuxt front-end located in the `client` directory.

## Backend Environment Variables

The following environment variables are used to [configure the Laravel](https://laravel.com/docs/11.x/configuration) application (OpnForm's API).

### Dedicated guides
There are dedicated configuration pages available for more detailed setup instructions on specific topics:
- [File Storage (S3)](../configuration/aws-s3)
- [Email Configuration (SMTP)](../configuration/email-setup)
- [Custom Domain](../configuration/custom-domain)
