| # This workflow is centrally managed in https://github.com/asyncapi/.github/ | |
| # Don't make changes to this file in this repo as they will be overwritten with changes made to the same file in above mentioned repo | |
| # This workflow will run on every comment with /update or /u. And will create merge-commits for the PR. | |
| # This also works with forks, not only with branches in the same repository/organization. | |
| # Currently, does not work with forks in different organizations. | |
| # This workflow will be distributed to all repositories in the AsyncAPI organization | |
