== Preface

The GlassFish Server Open Source Edition Administration Guide provides
instructions for configuring and administering
GlassFish Server Open Source Edition.

This preface contains information about and conventions for the entire
GlassFish Server Open Source Edition (GlassFish Server) documentation set.

GlassFish Server 7 is developed through the GlassFish project
open-source community at https://github.com/eclipse-ee4j/glassfish.
The GlassFish project provides a structured process for developing the
GlassFish Server platform that makes the new features of the Jakarta EE
platform available faster, while maintaining the most important feature
of Jakarta EE: compatibility. It enables Java developers to access the
GlassFish Server source code and to contribute to the development of the
GlassFish Server.
