<a name="welcome"></a>

Welcome to the Amazon SDK for C\$1\$1 Developer Guide.

The Amazon SDK for C\$1\$1 provides a modern C\$1\$1 (version C\$1\$1 11 or later) interface for Amazon Web Services (Amazon). It provides both high-level and low-level APIs for nearly all Amazon features, minimizing dependencies and providing platform portability on Windows, macOS, Linux, and mobile.
