Source code documentation

The Gekko source code is freely available (under the open-source GNU GPL licence) and is located on GitHub. The source code has a corresponding source code documentation:

• Source code documentation (Gekko 3.1.12). Published in 2021.
• Old documentation (Gekko 2.0). Published in 2014.

There is an API documentation available, too:

• API documentation (Gekko 3.1.12). Published in 2021.

The API documentation documents classes, fields, methods, etc., among other things what goes in and out of methods. But the source code documentation is in most cases the best place to start.
