-### Default Configuration
-
-#### Default Excluded Directories
-```python
-DEFAULT_EXCLUDE_DIRS = {
-    ".git", "node_modules", "__pycache__", "assets",
-    "img", "images", "dist", "build", ".next",
-    ".vscode", ".idea", "bin", "obj", "target",
-    "out", ".venv", "venv", ".gradle",
-    ".pytest_cache", ".mypy_cache", "htmlcov",
-    "coverage", ".vs", "Pods"
-}
-```
-
-#### Default Excluded Files
-```python
-DEFAULT_EXCLUDE_FILES = {
-    ".pyc", ".pyo", ".pyd", ".DS_Store",
-    ".gitignore", ".env", "Thumbs.db",
-    "desktop.ini", "npm-debug.log",
-    "yarn-error.log", "pnpm-debug.log",
-    "*.log", "*.lock"
-}
-```
-
-#### Default MarkItDown Extensions
-```python
-MARKITDOWN_EXTENSIONS = {
-    ".pdf", ".docx", ".xlsx", ".xls",
-    ".pptx", ".html", ".htm", ".msg"
-}
-```
-
-## 📜 Output Format
-
-Readium generates three types of output:
-
-1. **Summary**: Overview of the processing results
-   ```
-   Path analyzed: /path/to/directory
-   Files processed: 42
-   Target directory: docs
-   Using MarkItDown for compatible files
-   MarkItDown extensions: .pdf, .docx, .xlsx, ...
-   ```
-
-2. **Tree**: Visual representation of processed files
-   ```
-   Documentation Structure:
-   └── README.md
-   └── docs/guide.md
-   └── src/example.py
-   ```
-
-3. **Content**: Full content of processed files
-   ```
-   ================================================
-   File: README.md
-   ================================================
-   [File content here]
-

-   ```
-
-### Error Handling
-
-Readium provides robust error handling through the `error_handling` module:
-
-- Console-based error reporting with Rich formatting
-- Fallback handling for markup-containing error messages
-- Automatic handling of unprintable content with file output
-- Debug logging for troubleshooting issues
-
-## 🛠️ Development
-
-1. Clone the repository
-2. Install development dependencies:
-   ```bash
-   # Using pip
-   pip install -e ".[dev]"
-
-   # Or using Poetry
-   poetry install --with dev
-   ```
-3. Install pre-commit hooks:
-   ```bash
-   pre-commit install
-   ```
-
-### Running Tests
-
-```bash
-# Run all tests
-pytest
-
-# Run tests without warnings
-pytest -p no:warnings
-
-# Run tests for specific Python version
-poetry run pytest
