    After the PR being merged to `master`, you can use streamnative-ci to release the artifacts.
 
+   The streamnative-ci needs the specified tag, so we need to push a tag `vX.Y.Z.M` first, as well as the branch:
+
+   ```bash
+   $ git clone [email protected]:streamnative/kop.git
+   $ cd kop
+   $ git checkout -b branch-X.Y.Z
+   $ git push origin branch-X.Y.Z
+   $ git tag vX.Y.Z.M
+   $ git push origin vX.Y.Z.M
+   ```
+
+   Then use streamnative-ci to release the latest KoP:
+
    ```bash
-   $ git clone https://github.com/streamnative/streamnative-ci.git
+   $ git clone git@github.com:streamnative/streamnative-ci.git
    $ cd streamnative-ci
    $ git checkout release
-   $ git commit --allow-empty -m "/snbot release kop X.Y.Z.M"
+   $ git commit --allow-empty -m "/snbot release kop vX.Y.Z.M"
    $ git push origin release
    # Then, you can see the release process: https://github.com/streamnative/streamnative-ci/actions

-   Because the PR may contain multiple commits that will be squashed to a single commit, we need to overwrite the branch after the release.
