Netty 4.x User Guide

Netty 4.x User Guide is a Chinese translation and expanded edition of the official Netty 4 documentation. It introduces the asynchronous networking framework and explains its main architecture and development model. The material includes a preface, a getting-started section, an architectural overview, diagrams, and supplementary articles. Illustrations were added to make Netty’s channels, event loops, handlers, pipelines, and threading concepts easier to understand. Companion example code is maintained in a separate demonstration repository. Readers can access the guide through its GitHub source, a GitBook edition, or a dedicated website. Because the project reflects documentation from an earlier Netty 4 release period, it is especially useful as a foundational and historical learning resource.
