in plain english

Muduo is a network library written in C++ for building fast, multi-threaded server applications on Linux. A network library handles the low-level plumbing of accepting connections, sending and receiving data, and managing many simultaneous clients, so developers can focus on their application logic instead of re-implementing these basics from scratch. It is built around the reactor pattern, a common architectural approach where a single thread waits for network events (like an incoming message) and then dispatches them to worker threads for processing. This makes it well-suited for server software that needs to handle many concurrent connections efficiently. Muduo is aimed at C++ developers building backend server software on Linux who need a reliable, well-tested networking foundation. The README notes requirements of Linux kernel 2.6.28 or newer and a modern C++ compiler.
