This document provides an introduction and overview of Common.Logging, which is a logging abstraction library that allows switching between different logging frameworks. It discusses getting started by installing Common.Logging and adapter packages via NuGet, registering and configuring Common.Logging, configuring the adapter log, and writing logs using Common.Logging's simple API. The document also includes a reference section with links to additional Common.Logging resources.
