- The workflow can be run manually from the "Actions" tab in Github while viewing the Gloo OSS repo
+ - Ensure that PRs created from manual workflow runs are not merged by adding the "Work in Progress" tag or by making
+ the PR a draft.
- The user must specify three arguments, which should take the following values:
- `Use workflow from`: The branch in Gloo OSS which the generated Solo-APIs PR should mirror
