+# Structural Pages - Design Document
+
+## Overview
+
+The `structural_pages` module implements a hierarchical editorial structure and contextual navigation for institutional sites in Drupal 11. The module was designed for higher education institutions but is generic enough for other institutional contexts.
+
+## Problem
+
+In Drupal, content is added in a flat manner (non-hierarchical), and menus are traditionally used to organize content into hierarchical structures. This creates user experience problems because content editors typically do not have permission to administer menus.
+
+## Solution
+
+The module implements two complementary structures:
+
+1. **Taxonomic Structure** (primary): Organization based on hierarchical taxonomy vocabulary
+2. **Parent-Child Structure** (subsidiary): Direct hierarchy between pages for specific cases, supporting multiple entity types as parents
+
+See docs/DESIGN.md for details.
