A HelpStudio project contains all the information necessary to build a Help System. Every HelpStudio project contains:

• Conceptual Topics, including Topic content, links, and index keywords
• A Glossary containing Glossary terms and related definitions;
• A Table of Contents
• One or more Build Profiles that each define a particular output you want to produce from the project
• Zero or more Build Flags that can be used in Build Profile Rules to conditionally include items and content in a Build Profile
• Images, Stylesheets, and other files

Each project can optionally contain additional locales. Additional locales allow you to author content for multiple languages within a single project.

A HelpStudio project exists in a project directory that contains the main project file (with a .hsp extension), together with any project-specific image or other external files.
