+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+OpenGraphKt is a minimalist Kotlin multiplatform library for parsing Open Graph protocol tags from HTML. It wraps Ksoup (a Kotlin port of JSoup) to extract and structure Open Graph metadata.
+
+**Current Status**: Pre-alpha - Protocol implementation is complete for `og:` tags, but type system needs refinement.
+
+## Project Structure
+
+This is a multi-module Gradle project:
+
+- `opengraphkt/` - Core library module (published to Maven Central as `fr.lengrand:opengraphkt`)
+- `demo/` - Local file parsing examples
+- `demo-remote/` - Remote URL parsing examples (see Main.kt for usage)
+- `scrape-test/` - Testing/scraping utilities
+
+## Common Commands
+
+### Build and Test
+```bash
+./gradlew build                  # Build all modules
+./gradlew test                   # Run all tests
+./gradlew :opengraphkt:test      # Run tests for core library only
+```
+
+### Code Coverage
+```bash
+./gradlew koverXmlReport         # Generate XML coverage report
+./gradlew koverVerify            # Verify coverage meets 70% minimum threshold
+```
+
+### Publishing
+```bash
+./gradlew publishToMavenLocal    # Publish to local Maven repo for testing
+```
+
+## Architecture
+
+### Core Components
+
+**Parser (`Parser.kt`)**: Main entry point that accepts multiple input types:
+- `parse(url: URL)` - Fetches and parses remote HTML
+- `parse(html: String)` - Parses raw HTML string
+- `parse(file: File)` - Parses local HTML file
+- `parse(document: Document)` - Parses Ksoup Document
+
+The parser extracts `meta[property^=og:]` tags and builds structured data models.
+
+**Data Models (`Models.kt`)**: Type-safe representations of Open Graph data:
+- `Data` - Main container with `isValid()` method checking required fields (title, type, image, url)
+- Base types: `Image`, `Video`, `Audio`
+- Content-specific types: `Article`, `Book`, `Profile`
+- Music types: `MusicSong`, `MusicAlbum`, `MusicPlaylist`, `MusicRadioStation`
+- Video types: `VideoMovie`, `VideoEpisode`
+
+### Key Implementation Details
+
+**Tag Grouping**: Tags are grouped by namespace (prefix before first colon) to handle structured properties like `og:image:width`, `og:image:height` that belong to the preceding `og:image` tag.
+
+**Date Handling**: ISO 8601 datetime parsing with fallback for date-only formats (appends `T00:00:00Z`).
+
+**Structured Property Association**: Images/Videos/Audio with their metadata (width, height, type, etc.) are associated by parsing sequential tags - each base tag (`og:image`) is paired with following attribute tags (`og:image:width`) until the next base tag.
+
+## Development Notes
+
+- **JVM Toolchain**: Java 24 (see `jvmToolchain(24)` in build files)
+- **Testing**: CI matrix tests on Java 17 and 23 via GitHub Actions
+- **Dependencies**: Core library uses Ksoup (v0.2.5) for HTML parsing and network requests
+- **Maven Coordinates**: Group `fr.lengrand`, artifact `opengraphkt`, currently at `0.1.2-SNAPSHOT`
+- **Code Coverage**: Kover plugin enforces 70% minimum coverage threshold
