what I am meant to do with a github-based bugfix? (python-django on Win OS)

Not used to working collaboratively! I am gradually learning the mysteries of Git, but how you use github is still beyond me.

This relates to a bug with Django and Selenium as documented here: http://ift.tt/1NpIwUD

This takes us to this page on github: http://ift.tt/1NpIvQB

I "manually" added the new line ("refresh") to the file ...\admin\tests.py, and this seems to stop some of the ConnectionResetErrors occurring... but I don't know how to use this commit on github: in particular, the other file shown here, tests\view_tests\tests\test_i18n.py, doesn't exist, nor its path.

Am I meant somehow to "git pull" from github? And sort of replace my django file structure under "site-packages"?

I have a book on github (yes, an entire book!) and I will read it as soon as I can, promise.
