> **Note:** This project is developed with extensive AI assistance (GitHub Copilot, Claude). If you're also using AI tools, check [`AGENTS.md`](/AGENTS.md) for patterns and conventions that ensure consistency.

## Getting Started

1. **Fork the repository** on GitHub
2. **Clone your fork**:
   ```bash
   git clone https://github.com/YOUR_USERNAME/hass.tibber_prices.git
   cd hass.tibber_prices
   ```
3. **Open in DevContainer** (recommended):
   - Open in VS Code
   - Click "Reopen in Container" when prompted
   - Or manually: `Ctrl+Shift+P` → "Dev Containers: Reopen in Container"

See [Development Setup](docs/development/setup.md) for detailed instructions.

## Development Process

### 1. Create a Branch

```bash
git checkout -b feature/your-feature-name
# or
git checkout -b fix/issue-description
```

### 2. Make Changes

- Follow the [Coding Guidelines](docs/development/coding-guidelines.md)
- Keep changes focused and atomic
- Update documentation if needed

### 3. Test Your Changes

```bash
# Lint and format
./scripts/lint

# Start development environment
./scripts/develop

# Run tests (if available)
pytest tests/
```

### 4. Commit Your Changes

We use **Conventional Commits** format:

```
<type>(<scope>): <short summary>

<detailed description>

Impact: <user-visible effects>
```

**Types:** `feat`, `fix`, `docs`, `refactor`, `chore`, `test`

For full commit-message rules (including release-note skip trailers for internal/unreleased fixes), see:

- `.github/instructions/commit-messages.instructions.md`

Important trailers for commits that should NOT appear in release notes:

- `Release-Notes: skip`
- `User-Impact: none`
- `Released-Bug: no`

**Example:**

```bash
git commit -m "feat(sensors): add daily average price sensor

Added new sensor that calculates average price for the entire day.

Impact: Users can now track daily average prices for cost analysis."
```

See `.github/instructions/commit-messages.instructions.md` for detailed commit-message guidelines.

## Submitting Changes

### Pull Request Process

1. **Push your branch** to your fork
2. **Create a Pull Request** on GitHub with:
   - Clear title describing the change
   - Detailed description with context
   - Reference related issues (`Fixes #123`)
3. **Wait for review** and address feedback

### PR Requirements

- ✅ Code passes `./scripts/lint-check`
- ✅ No breaking changes (or clearly documented)
- ✅ Translations updated for all languages
- ✅ Commit messages follow Conventional Commits
- ✅ Changes tested in Home Assistant

## Coding Standards

### Code Style

- **Formatter/Linter**: Ruff (enforced automatically)
- **Max line length**: 120 characters
- **Python version**: 3.13+

Always run before committing:

```bash
./scripts/lint
```

### Key Patterns

- Use `dt_util` from `homeassistant.util` for all datetime operations
- Load translations asynchronously at integration setup
- Enrich price data before exposing to entities
- Follow Home Assistant entity naming conventions

See [Coding Guidelines](docs/developer/docs/coding-guidelines.md) for complete details.

## Documentation

Documentation is organized in two Docusaurus sites:

- **User docs** (`docs/user/`): Installation, configuration, usage guides
  - Markdown files in `docs/user/docs/*.md`
  - Navigation via `docs/user/sidebars.ts`
- **Developer docs** (`docs/developer/`): Architecture, patterns, contribution guides
  - Markdown files in `docs/developer/docs/*.md`
  - Navigation via `docs/developer/sidebars.ts`

**When adding new documentation:**

1. Place file in appropriate `docs/*/docs/` directory
2. Add to corresponding `sidebars.ts` for navigation
3. Update translations when changing `translations/en.json` (update ALL language files)

## Reporting Bugs

Report bugs via [GitHub Issues](../../issues/new/choose).

**Great bug reports include:**

- Quick summary and background
- Steps to reproduce (be specific!)
- Expected vs. actual behavior
- Sample code/logs if applicable
