| # This workflow builds versioned copies of Prefect's documentation. | |
| # It is triggered automatically by two events in PrefectHQ/prefect: | |
| # | |
| # 1. A new release is published | |
| # 2. A new commit is pushed to main branch's docs directory | |
| # | |
| # It also can be triggered manually by a user with write access to | |
| # the PrefectHQ/docs repository. In this case, the user must provide | |
| # a version number as an input to the workflow. | |
| name: Documentation Build | |

| # Limit concurrency by workflow/branch combination. | |

| # For pull request builds, pushing additional changes to the | |
| # branch will cancel prior in-progress and pending builds. | |
| # | |
| # For builds triggered on a branch push, additional changes | |
| # will wait for prior builds to complete before starting. | |
