 Many operating systems have an `open` command (though the name "open" is not ubiquitous); this means you can run something like `open $(harmony branch)` to open a web browser to the current branch on GitHub.
 
 ### PR
-Running `harmony pr [--draft] [#label, ...]` with a branch checked out will reach out to GitHub to determine if there is an open PR for that branch. If there is a PR, Harmony will print a URI that can be used to view the PR. If there is not a PR, Harmony will help you create one. New PRs can be created as drafts by specifying the `--draft` flag with the `pr` command.

 If you need to create a PR still, you will be prompted for a branch to open the PR against (merge into, eventually), a title for the PR, and a description for the PR. If you have an `EDITOR` environment variable set, Harmony will use that editor to get the PR description from you. If you have a PR template at `.github/PULL_REQUEST_TEMPLATE.md`, Harmony will also preload that into your editor. If you do not have an `EDITOR` environment variable set, you will still be able to enter a description from the command line but PR templates are only supported when an `EDITOR` is specified.
