# Overview

DocInsight is a local-first documentation system for building product documentation. It supports Markdown topics, API reference generated from Delphi source code, or both, and builds documentation websites, offline HTML, and CHM help.

The DocInsight command-line interface (CLI) is the primary way to initialize, check, build, open, and clean documentation projects, and to integrate documentation builds into CI workflows. For Delphi projects, the Delphi IDE extension helps you write and maintain XML documentation comments alongside the source code.
