I have a local sl repository which I want to push to github.

The basic commands have nothing on push.
The push documentation seems to assume that you have a remote added already.

The Git cheat sheet says that the equivalent of git remote add REMOTE URL is sl path --add REMOTE URL.
When I do that, I get abort: invalid URL - invoke as 'sl paths -a NAME URL'.
When I do sl paths -a <my url> I get the same error message.

How does this work?
