+### 🧠 What is Mindvas?
+
+Mindvas is an Obsidian plugin that transforms the built-in Canvas into a complete mind mapping tool. If you've used apps like XMind, FreeMind, or MindNode but wanted your mind maps to live inside your vault alongside your notes, Mindvas bridges that gap.
+
+Canvas gives you a great visual foundation, but it doesn't know about trees. Mindvas adds the missing layer: tree-aware keyboard shortcuts, automatic node layout, an outline sidebar, branch colors, and everything else you'd expect from a dedicated mind mapping app — stored as standard Obsidian Canvas files.
+
+### 🤔 Why Mindvas?
+
+* **Lives in your vault** — mind maps are regular `.canvas` files alongside your notes, not a separate app
+* **Keyboard-first** — add children, siblings, navigate, delete, and re-layout without touching the mouse
+* **Contour-based auto-layout** — packs nodes tightly as the map grows, with left/right branch support
+* **Outline panel** — sidebar with search, drag-and-drop, groups, and bidirectional highlight sync
+* **Runs locally** — no network requests, no telemetry, no external services
+
 ### ✨ Features
 
 * **Keyboard-driven editing** — Add, delete, and navigate nodes entirely from the keyboard
