Keeping up to date and previewing

To keep your clone up to date, all you have to do is click on the blue "pull" arrow in RStudio.

Getting branches to review

I will be giving you branches to review. To get those, you will have to open your Terminal.app, go to the place you've saved this repository and type:

git checkout master
git fetch
git checkout branchname # replace this with the actual branch name (e.g. introduction-outline)

Now you can view it from Rstudio by hitting the "Knit" button.

Making comments,

In this pull request, what I want you to do is click on the "files changed" tab up above and to your right.

If you have a comment, you can click on the line number next to the line you want to make a comment on and make your comments. Don't worry about attempting to change the file itself. It will be easier for me to integrate your comments as opposed to trying to work around edits and changes.
