# Environment Variables

Environment variables are key-value pairs used to configure applications dynamically without modifying code. For Apps on Clouddley, there are two modes for managing environment variables:

* **Single Variable:** Manually add individual environment variables.
* **Import Variables:** Bulk import multiple environment variables for easier management.
