[git] How do I get the latest version of my code?

If you are using Git GUI, first fetch then merge.

Fetch via Remote menu >> Fetch >> Origin. Merge via Merge menu >> Merge Local.

The following dialog appears.

Select the tracking branch radio button (also by default selected), leave the yellow box empty and press merge and this should update the files.

I had already reverted some local changes before doing these steps since I wanted to discard those anyways so I don't have to eliminate via merge later.
