Yes, Nano Banana 2 has official documentation hosted on its project website. The documentation covers installation, configuration, the full API reference for each supported language SDK, plugin development, and deployment guides. It is structured into a getting-started section aimed at new users, a how-to guide section for common tasks, and a reference section for developers who need detailed specifications. The documentation is versioned alongside the library, so you can always read the docs that correspond to the version you have installed.
The API reference is generated directly from source code annotations, which keeps it in sync with the actual implementation. Each public function and class includes a description, parameter types, return types, and at least one usage example. For the Python SDK, the generated documentation is also available as a companion to IDE tooling through standard docstring conventions, so you can access it inline in editors like VS Code or PyCharm without leaving your development environment.
The project also maintains a changelog that describes what changed between each release, including breaking changes, deprecations, new features, and bug fixes. If you are upgrading from a previous version, reviewing the changelog is the recommended first step. For topics not covered in the official documentation—such as advanced deployment configurations or unusual integration patterns—the GitHub Discussions forum is an active resource where both maintainers and community members answer questions.
