At the top level of the Scriptor installation the folder structure looks like:

.htaccess
imanager.php
boot.php
index.php    
data/
editor/
imanager/
site/

data/

This folder contains your site data like the datasets, backups, configurations, cache and logs.

editor/

This is the admin area of the Scriptor. In this folder, you will spend your time creating content.

imanager/

The imanager folder contains the ItemManager library that Scriptor relies on.

site/

This folder contains the theme of the website and your custom modules. Theme converts the content you have constructed into the HTML and displays it to your audience. There is a base theme that is provided with Scriptor, but you can even create your own. The Themes chapter will outline this in further detail.
