Welcome to our video series on learning version control with Git. Today, you'll see how you can use tags in Git. Tags allow you to mark important points in your project's history - for example a release.

A plain "git tag" shows you an alphabetical list of your tags.

Now, let's mark our current commit by tagging it as "version 1". Simply type "git tag" and the name. Any time later, we can run "git show" if we want to know which commit we attached that tag to.

Without any further arguments, the "git tag" command creates a "lightweight" tag. This means that the tag only knows which commit it's attached to. Nothing more.

If you add the "-a" parameter, in contrast, you'll create a so-called "annotated" tag. This has a couple of advantages. First, you can add a message with the "m" parameter:
git tag dash a 2.0 and a message.

Let's look at this tag with "git show":

You'll notice that an annotated tag also saves when it was created and by whom. That's why I'd always recommend adding that -a parameter when creating tags.

In case you want to add a tag to an earlier commit, you can simply add a hash to the end of the command.

And, in case you want to delete a tag, simply use the "-d" parameter:
