dispatch.sr.ht supports various integrations with GitHub. Some tips are provided here.
If you choose the "auto-merge" setting, builds.sr.ht will attempt to merge the pull request once the build completes successfully. You will likely want to add branch protection rules on GitHub to prevent this from happening before the pull request is reviewed.
To edit your branch protection rules, start by visiting "Branches" in your repository's settings.
Select "Add rule".
Specify the branches you want the rule to apply to (e.g. "master") and configure the criteria which must be met for the pull request to be mergeable. For example, to require the code to be reviewed before merge:
Important: if your account is an administrator on this GitHub repository, attempts to merge will succeed even if the branch protection rules are unmet. You must enable the "Include administrators" option to prevent this.
