+# Given facts:
+# * We don't allow manual tagging, but let the workflow create them after tests have passed.
+# * We don't let workflows be triggered by events coming from tags
+# * We use `npm run release` (without automated tagging) which only bumps version and creates changelog and commit message with title 'chore(release): v${semverVersion}'
+# * Pipeline detects the release title and after tests pass, creates artifacts (images) and makes full tag copies (and github release) to allow release patching.
