This is pretty basic, but the user interface does not make obvious what to do. I did not use SourceTree much.
There is only a "master" branch. A file has a conflict on a single line. Trying to do either a Pull or a Merge shows the file, with two versions of the line (with + and - signs). Now what? I want to tell SourceTree to just pull the updated file from the repository, but how can I do that?
