content tools web server

[petrmalkov]

as a newcomer with ContentTool I could not find anywhere answer

after tuning with http://getcontenttools.com/tutorials/saving-strategies
I realized that

    /site
        /html
            index.html
            about.html
        /static
            content-tools.css
            content-tools.js
            site.js
        app.py

app.py lays on top and what web server should parse it?

I thought it could be apache2 with flask
like here

I successed in Hello world
and tried to put in flask structure app.py /html /static
and failed because it lays in long path
/var/www/FlaskApp/FlaskApp/app.py

What instructions I missed?
Whatere to start from, what to fix, any ideas
Thank you in advance
