How to Create and Delete Git Tags in GitHub Repository

git tag is used to tag or mark a specific revision as significant, often this will be used during the build deployment and realsing of the code.  Once a tag is created, it’s often referred to by build and deploy scripts instead of the tag’s represented commit.  We can now easily create and delete git tags in GitHub.
