+## Detailed Guide
+
+### What this package provides
+Morphing polygon LoadingIndicatorM3E with Default and Contained variants, aligned with Material 3 Expressive motion and color tokens.
+
+### Installation
+- Monorepo (local path): already configured alongside m3e_design.
+- Pub (when published):
+```yaml
+dependencies:
+  loading_indicator_m3e: ^0.1.0
+  m3e_design: ^0.1.0
+```
+
+Minimum SDK: Dart >=3.5.0; Flutter >=3.22.0.
+
+### Dependencies
+- flutter
+- m3e_design
+- material_new_shapes
+
+### Quick start
+```dart
+// Default (indeterminate)
+const LoadingIndicatorM3E()
+
+// Contained variant (e.g., inside a container)
+const LoadingIndicatorContainedM3E(width: 48, height: 48)
+```
+
+### Key parameters
+- size / width / height: dimensions of the indicator.
+- color: Color? — Override the token-driven color.
+- semanticsLabel: String? — Describe what is loading for screen readers.
+
+### Theming with m3e_design
+Colors and easing come from tokens in M3ETheme; motion aligns with Material 3 Expressive guidelines.
+
+### Accessibility
+- Provide semanticsLabel to announce loading; avoid infinite animations for long periods.
