# Deploy Environment Variables

Applications can run in different configurations in various projects. For example, an application can work in two different projects with different default languages. For such requirements, the **Environment Parameters** feature of ACC is used. These parameters can be seen in the `ENV Variables` column when listing applications.

```bash
$ akinoncli projectapp add-env --deploy {project_id} {project_app_id} {ENV_KEY}={ENV_VALUE} {ANOTHER_ENV_KEY}={ANOTHER_ENV_VALUE}
```

**Environment Parameters**

Adds the environment parameter on the application.
