+name: Ensure CI is Enabled
+# This workflow allows a project to disable workflows based on a repository or
+# organizational environment variable. 
+#
+# Create a repo or org environment variable with its value set to 'true'
+# for this workflow to succeed. Any other value should cause this workflow
+# to fail.
+#
+# https://docs.github.com/en/actions/learn-github-actions/variables#creating-configuration-variables-for-a-repository
+#
+# Example usage, assuming this workflow is local to your repository:
+#
+# jobs:
+#   ensure_ci_enabled:
+#     uses: ./.github/workflows/check-ci-enabled.yml
+#     with:
+#       is-enabled: ${{ vars.CUSTOM_VAR_CI_ENABLED }}
+#
+#   next_task:
+#     needs: ensure_ci_enabled
+#     runs-on: ubuntu-latest
+#     steps:
+#     - ...
