Check a package

Will it install?

Give this a repository and a revision and it reads your package.ron at that exact point, then checks it against the rules the editor enforces when somebody clicks Install. No account, nothing saved, run it as often as you like.

The https URL you would clone. GitHub can be checked here automatically.
A tag is the right answer for a release. A branch moves, and takes your version number with it.
Only if package.ron is not at the top of the repository.
