Add image guide for watching repositories

[jbtill]

Problem

In Step 0 - Introductory Steps when it asks the user to look for the "Watch" button when you are in a repository, it may be useful to provide a screenshot showing where exactly the user will click. I also noticed that in this step, it mentions to "Click on the image to enlarge", yet there is no image present. Perhaps there was actually meant to be an image here showing the user how to watch repositories?

Steps to reproduce the problem

N/A

Screenshots

Proposed solution

Add a screenshot to the step that shows users where on the page to click to follow a repository.

This would certainly help make it a little clearer about where the "Watch" and "Follow" buttons are.

If images would be too big maybe the paragraph could be rewritten to something a little more specific
