+
+## Project Overview
+
+Hyperdash Angular (`@hypertrace/hyperdash-angular`) is an Angular library providing dashboard runtime capabilities. It wraps the core `@hypertrace/hyperdash` library with Angular services, components, and directives.
+
+**Structure**: Monorepo with a publishable library (`projects/hyperdash-angular/`) and demo app (`src/`).
+
+## Common Commands
+
+```bash
+# Development
+npm start                    # Dev server at localhost:4200
+npm run build               # Build app and library
+
+# Testing
+npm test                    # Run tests (watch mode)
+npm run test:ci:lib         # Library tests only (CI mode)
+npm run test:ci:app         # App tests only (CI mode)
+npm run test:ci             # Full CI suite (lint + all tests)
+
+# Code Quality
+npm run lint                # Run ESLint
+npm run commit              # Interactive conventional commit (commitizen)
+```
+
+## Architecture
+
+### Injectable Wrappers Pattern
+
+Core `@hypertrace/hyperdash` classes are wrapped as Angular injectable services following the pattern `[ClassName]Service`:
+
+- `DashboardManagerService`, `ModelManagerService`, `ThemeManagerService`, etc.
+- Always use the service wrapper (e.g., `DashboardManagerService`) rather than the core class directly.
+
+### Module System
+
+- `DashboardCoreModule`: Main runtime module with default property types and deserializers
+- `DashboardCoreModule.with(metadata)`: Extend with custom types, models, renderers, editors, deserializers
+- `DashboardEditorModule`: Separate module for editing capabilities
+
+### Key Injection Tokens
+
+- `MODEL_PROPERTY_TYPES`: Register custom property types
+- `DASHBOARD_DESERIALIZERS`: Register custom deserializers
+
+### Rendering
+
+- `DashboardComponent` (`<hda-dashboard>`): Main rendering component
+- `DashboardModelDirective` (`hdaDashboardModel`): Injects models into template context
+- `ThemePropertyPipe`: Theme-aware property rendering
+
+## Code Conventions
+
+### Selectors
+
+- **Library components**: `hda-*` prefix (kebab-case)
+- **Library directives**: `hda*` prefix (camelCase)
+- **App components**: `app-*` prefix
+
+### TypeScript
+
+- Strict mode enabled with `noUnusedLocals`, `noUnusedParameters`, `strictNullChecks`
+- Explicit access modifiers required (public/private/protected)
+- No `any` types allowed
+- Parameter properties preferred: `constructor(private readonly service: Service)`
+
+### Testing
+
+- Jest with `@ngneat/spectator` for component testing
+- Test files: `*.test.ts` or `*.spec.ts`
+- Coverage excludes: `*.module.ts`, `public_api.ts`, `test/` directory
+
+### Commits
+
+- Conventional commits required (enforced via commitlint)
+- Use `npm run commit` for interactive commit wizard
+- Pre-commit hook runs Prettier on staged files
+
+## ESLint Rules of Note
+
+- Max 500 lines per file
+- Template conditional complexity: max 4
+- Template cyclomatic complexity: max 5
+- No inline templates > 10 lines
+- Arrow functions: `as-needed` body style
+- Prefer template literals over string concatenation
