 ## Introduction
 
-[Environmental variables]('/definitions/20241126_definition_environment_variables.md') are important for configuring development environments and storing sensitive information. They provide a flexible way to control application behavior without hardcoding values directly into the source code. Daytona offers a streamlined method for setting, managing, and using environmental variables across various workspaces using the `daytona env` command. This simplifies configuration and enhances security especially when collaborating on projects.
