-
-Perform a dry-run push first to make sure the correct branch and only our tag

-    $ git push --dry-run --tags origin v0.11.4rc  # tags and branch

-An alternative is to push branch and tags separately:
-
-    $ git push --dry-run origin v0.11.4rc  # the branch
-    $ git push --dry-run origin v0.11.4rc1  # the tag

-Verify that the output corresponds to what you actually wanted to push;
-the correct branch and tag, etc.

-Remove `--dry-run` when you're happy with the results.
+Use the [Semaphore CI tag-release task](https://semaphore.ci.confluent.io/projects/clients-releases/schedulers/30e1eb9a-91de-43a4-a8de-be4f3de5a3b6) to create tags. Set the parameter accordingly:
+- **PROJECT**: confluent-kafka-python
+- **GIT_REF**: name of your RC branch (`v0.11.4rc` in this tutorial)
+- **TAG_NAME**: name of the new tag (`v0.11.4rc1-dev1`, for example)
+- You can do a test run (set **dry_run** to true) to verify the output before proceeding with the actual tag creation (set **dry_run** to true).
