+# Project Roadmap Timeline Component
+
+## 1. What does this do?
+Provides a highly responsive, interactive, and visually polished project roadmap timeline component that tracks progress milestones (Completed, In Progress, Upcoming) with glassmorphic cards and spring-bounce animations.
+
+---
+
+## 2. How is it used?
+Construct a timeline using the following semantic classes. No JavaScript required.
+
+```html
+<!-- Main timeline container (renders horizontal on desktop, vertical on mobile) -->
+<div class="rt-timeline" role="list" aria-label="Roadmap milestones">
+
+  <!-- Individual item (can be: rt-item--completed, rt-item--active, or rt-item--upcoming) -->
+  <article class="rt-item rt-item--active" role="listitem">
+
+    <!-- Milestone progress dot -->
+    <div class="rt-marker">
+      <span class="rt-dot rt-dot--pulse">
+        <span class="rt-dot-inner"></span>
+      </span>
+    </div>
+
+    <!-- Detailed information card -->
+    <div class="rt-card">
+      <span class="rt-badge rt-badge--active">In Progress</span>
+      <h2 class="rt-title">Core Development</h2>
+      <p class="rt-desc">Milestone details go here.</p>
+      <time class="rt-date" datetime="2026-06">Jun 2026</time>
+    </div>
+
+  </article>
+
+</div>
+```
+
+---
+
+## 3. Why is it useful?
+Roadmaps and progress stepper components are standard for landing pages, product pages, and developer dashboards, but they are difficult to code responsively. 
+
+This component features:
+- **Responsive Layout Shifting:** Automatically lays out steps horizontally on desktop viewports (>768px) and switches to vertical layouts on tablets and mobile screens using fluid grid metrics and no JavaScript.
+- **High-fidelity Micro-interactions:** Applies a bouncy spring curve (`cubic-bezier(0.34, 1.56, 0.64, 1)`) on card-lifts and dot scaling to match EaseMotion's snappy feel.
+- **State-aware Connecting Connectors:** The timeline connecting bar transitions dynamically between states (green for completed, blue-to-gray gradient for in-progress, dark gray for upcoming).
+- **Accessibility Audit Compliant:** Employs explicit ARIA role list/listitem annotations, semantic layout tags, keyboard-friendly outline hints, and complete `@media (prefers-reduced-motion: reduce)` resets.
