Private (or "3rd party") Component Registry?

[gamename]

Hi,

Has anyone succeeded in creating their own registry? If so, how? I've been going over the docs and it isn't clear if that's possible. Basically, I want to have my own collection of components to pull with `idf.py add-submodule`.

Or, should I just create component repos and add them as submodules manually?

Thanks,
