Today I had to read about git tags in order to be able to explain in a better way why somebody would use tags and for what. The old (and still good) git workflow explains very well how to develop using branches but doesn’t explain too well why we create the tags and how should be used on production. It just saying “that commit on master must be tagged for easy future reference to this historical version”. If you followed that guide and now you are ready to go live with your code changes, you maybe wonder what should you do with the tag? Why did you create it. Some people would say, just leave it there, maybe somebody, in a shiny day will take a look to it. Just go to production and do git pull origin master. But I don’t think this is the purpose of the tag.
