As of July 2020, as clarified by [How to Update Winget Source List][1]:

> Winget is a really young application in terms of software age and currently, only has a single source/repo available for it, Microsoft's official Winget repository.
>
> *Thus sub-commands such as `add` and `remove` aren't of use yet.*

Microsoft announced and open-sourced [winget](https://github.com/microsoft/winget-cli), a package manager for Windows.

When entering `winget source` (after installing it), it can be seen that it supports adding sources.

`winget source` provides the following subcommands:
```
add     Add a new source
list    list current sources
update  updates current sources
remove  removes current sources
reset   resets sources
```
By entering `winget source list`, the default source is displayed (as long as the sources were not changed):
```
C:\Windows\System32>winget source list
Name   Arg
-----------------------------------------
winget https://winget.azureedge.net/cache
```

As sources can be added using `winget source add`, how can source repositories be created?

How does a repository has to be structured or is there just not enough documentation to answer this question?

<sub>I think this question is on-topic for Stack Overflow as the main reason to add sources is (in my point of view) to create alpha/beta channels for programs or similar.</sub>
