So here is my flask site 
But, getting to this point is a longer explanation.
First, I couldn't get my 'about' section to work. Everytime I tried to view it, I kept getting this 
I looked up this error message, and all the boards said it was because flask couldn't find the about function so it didn't know what it was supposed to be doing. I couldn't understand since I had done what the instructions said. However, when I talked to Elliott, he explained that since I had the @app.route at the end of the flaskr.py file that it wasn't reading right. The last statement needs to be if name == 'main': init_db() app.run() because that corresponds to the beginning tag and the code knows to look for that if statement and read everything in the file and process it. Since I had my 'about' section underneath this, the program wasn't even reading it.
But, this problem led to a bigger problem when I tried to post the problem code on github. I kept getting email after email saying 'page build error' and when I ran jekyll serve --watch, I kept getting something about angle brackets or a block. This is one of the many error messages I received 
Elliott posted to the Google Plus page that the way to solve it would be to add and tags around my code so that Liquid would quit trying to process the code and just show it like I wanted to. The finished code looks like the below.
In my templates/layout.html:
<!doctype html>
<title>Flaskr</title>
<link rel=stylesheet type=text/css href="{{url_for('static', filename='style.css')}}">
<div class=page>
<h1>Flaskr</h1>
<div class=metanav>
#Add this line:
<a href="{{url_for('about')}}">about</a>
{% if not session.logged_in %}
<a href="{{ url_for('login') }}">log in</a>
{% else %}
<a href="{{ url_for('logout') }}">log out</a>
{% endif %}
</div>
{% for message in get_flashed_messages() %}
<div class=flash>(( message ))</div>
{% endfor %}
{% block body %} {% endblock %}
</div>
Overall, this was an informative, if entirely frustrating process.
