Each Git commit is uniquely identified by a hash e.g., d670460b4b4aece5915caf5c68d12f560a9fe3e4. As you can imagine, using such an identifier is not very convenient for our day-to-day use. As a solution, Git allows adding a more human-readable tag to a commit e.g., v1.0-beta.

Here's how you can tag a commit in a local repo (e.g. in the samplerepo-things repo):

SourceTree

Right-click on the commit (in the graphical revision graph) you want to tag and choose Tag….

Specify the tag name e.g. v1.0 and click Add Tag.

The added tag will appear in the revision graph view.

---

CLI

To add a tag to the current commit as v1.0,

git tag –a v1.0

    

    


    
    

To view tags

git tag

    

    


    
    

To learn how to add a tag to a past commit, go to the ‘Git Basics – Tagging’ page of the git-scm book and refer the ‘Tagging Later’ section.

Remember to push tags to the repo. A normal push does not include tags.

# push a specific tag
git push origin v1.0b

# push all tags
git push origin --tags

After adding a tag to a commit, you can use the tag to refer to that commit, as an alternative to using the hash.
