+#### Job Token
+If you do not provide a PAT the [job token](https://docs.gitlab.com/ee/ci/jobs/ci_job_token.html) will be used.
+This restricted token can create releases but not read commits. The [git strategy](https://docs.gitlab.com/ee/ci/runners/configure_runners.html#git-strategy)
+must be set to clone so that we can read the commits from the repository. See example below
+
+.gitlab-ci.yml
+```yml

+  GIT_STRATEGY: clone

+stages:
+  # other stages
+  - release

+release:

+    # - semantic-release --allow-no-changes # create a release for each push
+    # - semantic-release --provider gitlab --provider-opt log_order=ctime # traverse commits by committer time (commits in merge requests will affect the calculated version)
