#### Runtime environment variables
If an `.env` file containing environment variables is present when the build process is run, these values will be hard-coded in the output, just as when generating a static website.
During the build, the runtime variables must be absent from the `.env` file, and you must provide Astro with every environment variable to expect at run-time: `VARIABLE_1=placeholder astro build`. This signals to Astro that the actual value will be available when the built application is run. The placeholder value will be ignored by the build process, and Astro will use the value provided at run-time.
In the case of multiple run-time variables, store them in a seperate file (e.g. `.env.runtime`) from `.env`. Start the build with the following command:
```sh
export $(cat .env.runtime) && astro build
```
