+# This release script determines if a publish should happen using a dry run of semantic release to determine if the
+# commits contain publishable changes (feat, bug, breaking change). If so, lerna will be used to perform the actual
+# publish, however, lerna also has its own logic for determining whether to publish. Specifically, it will run git diff
+# in each package, excluding markdown files, tests, etc. So any attempt to force a version bump with an empty commit or
+# readme tweak will fail. To get around this, we pass the `force-publish` option to lerna, skipping the git diff for
+# changed packages. This allows the semantic release dry run check to be the deciding factor for publishing.
