Tagging a git repo for a Release

I think it is good practise to create a read only tag when releasing an application. This allows you to create a branch from it at any time or a bug fix with out worrying about accidentally mixing in new features from your latest code base.

Git Tagging

Lists current tags:

$ git tag 

Create tag named gem-0.1.0, code to match the gem 0.1.0 release.

$ git tag gem-0.1.0 

Push named tag to the remote repo:

$ git push origin gem-0.1.0

Push all tags to repo:

$ git push --tags
