-!!! note
-    Unlike features which affect how the project itself is installed, dependency groups are separate dependencies that are installed alongside the project.

 ### Dev mode
 
 By default, environments will always reflect the current state of your project on disk, for example, by installing it in editable mode in a Python environment. Set `dev-mode` to `false` to disable this behavior and have your project installed only upon creation of a new environment. From then on, you need to manage your project installation manually.
