Unclear Message asking for paths

I'm trying to create a new cli extension project from a blank foldre using azdev

It wasn't clear to me what "Input the paths for the extension repos you wish to develop for."

Can we update this message to explain what this means?

Are we asking for the paths to another folder that we want to place the cli extension project in?

What do you mean by "add as many repos as you like". Are you expecting that to be comma delimited? And why would I do multiple repos?

```
Do you plan to develop CLI extensions? (y/n): y

Great! Input the paths for the extension repos you wish to develop for, one per line. You can add as many repos as you like. (TIP: to quickly get started, press RETURN to use your current working directory).
```

When I click enter, I get this:
```
Path (RETURN to use current directory):
'C:\Users\jong\OneDriveMS\code\azure-cli-docs-extension' is not a valid git repository.

Path (RETURN to continue):
```

It looks like there's an expectation for the current directory to be a git repo. I wasn't told that up until now.

I hit enter, Then I get this:
```
TIP: you can manage extension repos later with the `azdev extension repo` commands.

Summary
=========

CLI: PyPI
Extension repos:
Extensions:
```

At this point, I haven't been told what 'extension repos' are and it's unclear what I should do next.
