-## Update a commit status per workflow
-
-start-action is run per job, so commit statuses are updated per job by default.
-To update commit statuses, start-action calls GitHub API so it may cause GitHub API rate limiting.
-If you'd like to decrease API call, you can update commit statuses per not job but workflow.
-To do so, please do the following things.
-
-- Set the environment variable `GHA_WORKFLOW_COMMIT_STATUS` to `true` in workflow scope
-- Set the parameter `start_workflow` to `true` at only one `start-action`
-- Remove `end-action` from all jobs except for the last job
-- Add a job to update a commit status at the end of workflow
-
-e.g.
-
-```yaml
-env:
-  GHA_WORKFLOW_COMMIT_STATUS: "true"
-jobs:
-  foo:
-    steps:
-      - uses: gha-trigger/start-action@main
-        id: start
-        with:
-          # ...
-          # commit status is changed to "pending"
-          update_commit_status: true # set this parameter at only this step
-      # ...
-  bar:
-    steps:
-      - uses: gha-trigger/start-action@main
-        id: start
-        with:
-          # ...
-          # Don't set the parameter `update_commit_status`
-          # commit status isn't changed
-      # ...
-  status-check:
-    runs-on: ubuntu-latest
-    needs: [foo, bar] # Run this job lastly
-    if: always()
-    steps:
-      - uses: gha-trigger/start-action@main
-        id: start
-        with:
-          # ...
-          # Don't set the parameter `update_commit_status`
-          # commit status isn't changed
-      - uses: gha-trigger/end-action@main
-        if: always()
-        with:
-          github_token: ${{steps.start.outputs.github_app_token}}
-          state: ${{job.status}}
