+Next Blog Documentation
+=======================
+
+Next Blog is a full-stack blog platform built with Next.js, Payload CMS,
+PostgreSQL, Drizzle ORM, better-auth, and Fuma Comments. This documentation
+tree describes the product intent, system architecture, runtime operations,
+frontend conventions, and contribution workflow for the repository.
+
+The structure intentionally follows a subsystem-oriented layout: top-level
+indexes introduce each area, while deeper pages describe concrete flows,
+interfaces, and operational responsibilities. Keep this page small; add new
+material under the nearest subsystem directory.
+
+Audience
+--------
+
+This documentation is written for:
+
+* maintainers who need to understand the shape of the codebase;
+* contributors who need repeatable setup and contribution rules;
+* operators who need environment, database, and release notes;
+* designers and frontend engineers who need UI conventions.
