+
+---
+
+This Python script is designed to automate the process of copying and modifying files and directories based on rules defined in a YAML configuration file.
+
+It's main intention is the ability to automate the modifying process of the Jellyfin web directory after every new release (take a look at [BobHasNoSoul-jellyfin-mods](https://github.com/BobHasNoSoul/jellyfin-mods)).
+
+Below is an overview of its main functionality and usage:
+
+## Features
+
+1. **Configuration Loading**:
+   - Reads a YAML configuration file specified as a command-line argument.
+   - Validates and parses the configuration to extract copy and modification rules.
+
+2. **Directory Management**:
+   - Ensures the existence of a specified destination directory where all operations will take place.
+
+3. **File and Directory Copying**:
+   - Supports multiple copy modes:
+     - **Replace**: Overwrites existing files or directories in the destination.
+     - **Update**: Copies only if the source file is newer than the destination file.
+   - Handles both files and directories.
+   - Generates warnings and error messages if issues occur (e.g., source file not found).
+
+4. **File Modifications**:
+   - Supports modifications to text files based on rules defined in the configuration file.
+   - Operations include:
+     - Inserting text before or after specific content.
+     - Replacing old text with new text.
+   - Recursively applies changes to files matching specified patterns in the destination directory.
+
+5. **Error and Warning Tracking**:
+   - Tracks the number of successful operations, errors, and warnings for both copy and modification processes.
+
+6. **User Feedback**:
+   - Provides detailed, color-coded output to indicate the progress and results of operations.
+   - ANSI escape sequences are used for colored terminal messages.
+
+
+## Usage
+
+### Prerequisites
+- Ensure Python 3.x is installed.
+- Install the PyYAML-Library (pip install pyyaml)
+
+### Configuration File
+Create a YAML file with the following sections:
+- `destination_directory`: Path to the target directory.
+- `copy_rules`: List of copy instructions (source paths, modes, and targets).
+- `modification_rules`: List of modification instructions (patterns, insertion, and replacement rules).
+
+### Simple example yaml
+For more details take a further look into config-TEMPLATE.yaml
+```yaml
+destination_directory: "./web"  # Target directory for operations
+
+copy_rules:
+  - sources:  # Files/folders to copy
+      - './source_folder' # Entire folder located from where you called the script
+      - source: "./src/file.js"
+        target: "./dist/file.js"
+    mode: "replace"  # Options: replace, update
+
+    - sources:
+          - './source_folder'  # Entire folder
+          - './specific_file.txt'  # Single file
+          - './source_directory/*.js'  # All JS files
+        mode: 'copy'  # Copies files/folders located from where you called the script
+
+modification_rules:
+  - file_pattern: "*.js"  # Files to modify (supports regex)
+    insert_rules:
+      - after_text: "search text"  # Insert after this text
+        insert_text: "new content"
+      - before_text: "target"  # Insert before this text
+        insert_text: "new content"
+    replace_rules:
+      - old_text: "original"  # Text to replace
+        new_text: "replacement"
+```
+
+### Running the Script
+Run the script by providing the path to your YAML configuration file, using the following command:
+```bash
+python script.py <path_to_config_file>
+```
+So for example:
+```bash
 python customize-WebUI.py config.yaml
-
-Requirements:
- - Python 3
- - PyYAML-Library (pip install pyyaml)
\ No newline at end of file
+```
