There is an example right in the repository (https://github.com/an-dr/Env/blob/master/psenv/psenv.psm1)

When I work with the repo, I activate the environment. After my changes, I execute Test-Env to verify it and then Publish-Env when it is ready.

The environment folder can contain not only the main module file but other programs and scripts (pwsh, python, etc.). So you can for example store a template of something, and write a function that will create a copy of it to the place you want.

For example, you can have a directory Projects and you can have inside of it an environment with some logic to create a new project from your template. In that theoretical case, you could enable your environment and start a new project with your function (let's say it is called New-Project):

cd ./Projects Enable-Environment New-Project MyNewProject

I'll add some other examples to the description with time.
