git add tag

You can run these steps via git-bash

1. Checking out master branch

   git checkout master

2. Tagging master branch to the version you are going to release

   git tag relese-vX.Y.Z

3. Show the tagged version

   git tag

   In case tagging wrong, you can delete tag with git tag -d release-vX.Y.Z

4. Push the tagged branch to origin

   git push origin --tags
