The Pineapple Example Modules project creates a JAR file which contains a compendium of example modules.
The JAR file is named pineapple-example-modules-<version>.jar.
The content of the archive will be unpacked into the modules directory when Pineapple is run without an existing configuration.
Alternatively the the archive can be downloaded and unpacked.
Technical documentation for developers about the architecture, design and implementation of the project can be found here.
