Minor suggestions for wording of issues

[jesse-ross]

Thanks for this awesome training - I really enjoyed it! I'm more used to working on branches than forks, and this made me feel totally confident.

I had a couple of minor suggestions:

• In issue 7, section 4, the way that issues numbers are referred to confused me. I wrote the square brackets, as in "#[7]", rather than "#​7". An example might be helpful here.
• In issue 14, section 3 it says “see image below” but there is no image.
• In issue 14, section 3 it says ‘At the top, click the "New pull request button".’ but I didn’t see that button on the code page. I had to create the pull request from the contribute pulldown.
