How to Create a New Local Branch from Existing Remote Tag

1. Make sure all the remote references are downloaded. I.e. use:
   
   $ git fetch
2. If there's any update, something like this should appear after git fetch:
   
   $ git fetch
   remote: Counting objects: 153, done.
   remote: Compressing objects: 100% (49/49), done.
   remote: Total 97 (delta 58), reused 87 (delta 48)
   Unpacking objects: 100% (97/97), done.
   From github.com:myproject/awesomewebsite
    + 22e503c...5e0ce5a maint      -> origin/maint  (forced update)
    ... something-something ...
    * [new tag]         1.3.84.7   -> 1.3.84.7
   From github.com:myproject/awesomewebsite
    * [new tag]         1.4.20.6   -> 1.4.20.6
   
3. Create the new branch in the form:
   
   $ git checkout -b <new branch name> <tag>
   
   For example, creating the new branch feature/awesomesauce from tag 1.4.20.6:
   
    $ git checkout -b feature/awesomesauce 1.4.20.6

If your repository is not updated (step 1), and it does not yet have the reference to the tag, Git will complain like so:

$ git checkout -b feature/awesomesauce 1.4.20.8
fatal: Cannot update paths and switch to branch 'feature/awesomesauce' at the same time.
Did you intend to checkout 'myproject/1.4.20.8' which can not be resolved as commit?
