- Installation describes how to install CGAL, and lists the third party libraries on which CGAL depends, or for which CGAL provides interfaces.
- Hello World presents you some short example programs to get a first idea for the look and feel of a program that uses CGAL. We introduce the notion of the kernel which defines geometric primitives, the notion of traits classes which define what primitives are used by a geometric algorithm, the notions of concept and model.
- Organization of the Manual gives an idea where you should look for documentation. The documentation for a class, may be spread over manual pages of base classes, and reference manual pages of concepts the class is a model of.
- Preliminaries lists the licenses under which the CGAL datastructures and algorithms are distributed, how to control inlining, thread safety, code deprecation, checking of pre- and postconditions, and how to alter the failure behavior.
