Cloning is used to download a project or branch for contributing to it. (To install a project dependency, use thepullcommand.) Unlike with Git workflows, where you clone a project and can download all the project's branches (stale or otherwise,) in Unison you clone specific branches of a project.
To clone a project from Unison Share, use theclonecommand. The first path segment is the user's Unison Share handle and the second is the name of the project.
.> clone @unison/projectNameUnless otherwise specified, the cloned project will only include themainbranch.
