# Now-env example

This example shows the usage of [Now Secrets](https://vercel.com/docs/v2/deployments/environment-variables-and-secrets/?query=secret#securing-environment-variables-using-secrets) and [now dev](https://vercel.com/docs/v2/development/basics), it shows how to add environment variables in development that can be replaced in production by the secrets defined with [Now](https://vercel.com/now).
