+
+## Prerequisites
+
+- Python 3.11 or higher
+- UV package manager (recommended) or pip
+
+## Installation Methods
+
+### Method 1: UV Tool Install (Recommended)
+
+This is the easiest way to install and use Renamer globally on your system.
+
+#### Install UV (if not already installed)
+```bash
+# On Linux/macOS
+curl -LsSf https://astral.sh/uv/install.sh | sh
+
+# On Windows
+powershell -c "irm https://astral.sh/uv/install.sh | iex"
+```
+
+#### Install Renamer
+```bash
+# From the built wheel (if available)
+uv tool install dist/renamer-0.2.0-py3-none-any.whl
+
+# Or from PyPI (when published)
+uv tool install renamer
+```
+
+#### Usage
+```bash
+renamer                    # Scan current directory
+renamer /path/to/directory # Scan specific directory
+```
+
+### Method 2: pip Install from Wheel
+
+If you have the wheel file, you can install it with pip.
+
+```bash
+# Install the wheel
+pip install dist/renamer-0.2.0-py3-none-any.whl
+
+# Or install globally (may require sudo)
+sudo pip install dist/renamer-0.2.0-py3-none-any.whl
+```
+
+### Method 3: Development Installation
+
+For development or if you want to run from source:
+
+#### Clone and Setup
+```bash
+git clone <repository-url>
+cd renamer
+
+# Install dependencies
+uv sync
+
+# Run directly
+uv run python main.py
+uv run python main.py /path/to/directory
+```
+
+#### Install in Development Mode
+```bash
+uv sync
+uv tool install --editable .
+```
+
+### Method 4: Direct Python Execution
+
+If you prefer not to install globally:
+
+```bash
+# Ensure you have Python 3.11+
+python3 --version
+
+# Install dependencies
+pip install textual mutagen pymediainfo python-magic langcodes
+
+# Run the application
+python3 main.py
+python3 main.py /path/to/directory
+```
+
+## System Requirements
+
+### Linux
+- Python 3.11+
+- MediaInfo library (for detailed media analysis)
+  ```bash
+  # Ubuntu/Debian
+  sudo apt install libmediainfo-dev
+
+  # Fedora/CentOS
+  sudo dnf install libmediainfo-devel
+
+  # Arch Linux
+  sudo pacman -S libmediainfo
+  ```

+python3 main.py --help
+```
+
+You should see the help text for the Renamer application.
+
+## Troubleshooting
+
+### Common Issues
+
+1. **"Command not found"**
+   - Ensure UV bin directory is in your PATH
+   - Try `uv tool install` again
+
+2. **Import errors**
+   - Ensure all dependencies are installed
+   - Try `uv sync` or `pip install -r requirements.txt`
+
+3. **Permission errors**
+   - Use `sudo` for system-wide pip installs
+   - Or use UV tool install which handles permissions
+
+4. **MediaInfo not found**
+   - Install system MediaInfo library
+   - Or use basic mode (limited functionality)
+
