The documentation only mentions how to checkout the repo that contains the YAML file. This is the main use case. It implies, however, that it is possible to checkout something other than self. What does the syntax for this look like (example)? If it is not possible to checkout something other than self, the documentation should say that.
checkout: self # self represents the repo where the initial Pipelines YAML file was found

Today we support checkout: self and checkout: none. In the future, it will be possible to checkout other repos.
@pollockm Until support is added for checking out other repos, you can accomplish this with PowerShell.
