There are two packages available.

Download the Designer package, if you want to build your own homepage on top of Macao. In most cases this will be the right one.

Download the Full package, if you want to modify or extend the core Macao functionality. This package is much larger, because it includes the editor for the API Documentation.

Both packages are including the source code, because JavaScript applications are ever including the source code.

Download the package via the >> Summary page << of the project.
