 # Diagram Tools
 
+Diagram Tools is a local, script-free editor for bounded flowchart, sequence,
+class, state, entity-relationship, mind-map and timeline sources. It provides
+line diagnostics, reusable examples, accessible outlines, pan/zoom, local
+source import/export, normalized JSON, inert SVG and local PNG export. Mermaid
+directives, styling, click handlers and external resources are never executed.
+
 Diagram Tools is a GPL-3.0-or-later local text/visual editor with an independent safe Mermaid-like subset for flowchart/graph, sequence, class and state diagrams. It produces deterministic SVG, a local 2× PNG, syntax diagnostics, scroll/drag pan, 25–300% zoom and an accessible textual outline.
 
-Supported syntax is deliberately small: node declarations/shapes and four edge styles; participants/messages; class declarations/members/relations; state nodes/transitions. Directives, clicks, styles, scripts, HTML and remote assets are rejected. Caps: 50,000 characters, 2,000 lines, 200 nodes, 500 edges, 2,400 px layout edge and 20 megapixel PNG.
