Git tagging.
Quick cheat sheet for referencing. Tags are a way to bookmark a particular version of your git repository for future referencing. Use them to bookmark stable and dev versions of your project.
$ git tag -l
$ git tag -a v1.1
$ git tag -a v1.0
$ git push --tags origin
Add a tag with inline message (no editor):
$ git tag -a v1.1 -m 'this is version 1.1'
Remove a tag:
$ git tag -d v1.1
You can also push tags with a regular push with the tags argument:
$ git push -u origin master --tags
Done!
