+## Introduction
 
-### Introduction
+A streamlined solution for managing MKV files, this program leverages MKVToolNix to modify audio and subtitle track properties without the need for time-consuming file reencoding. Users can easily set their track preferences, and the application intelligently applies the best matching configuration. The tool focuses on metadata modification rather than full file rewriting, ensuring quick operations while maintaining the original file integrity. This makes it an ideal choice for managing multilingual media collections or batch processing multiple MKV files.
 
-This program helps to change audio and subtitle lines of mkv files.
+![](https://github.com/RatzzFatzz/MKVAudioSubtitleChanger/blob/master/example.gif)
 
-### Requirements
+## Requirements
 
- - Java 11 or higher
+ - Java 21 or newer
  - mkvtoolnix installation
  
-### Running
+## Execution
+### Minimal usage
+Portable: `java -jar mkvaudiosubtitlechanger-<version>.jar --library "X:/Files" --attribute-config eng:ger eng:OFF`
+Windows & Linux (installed): `mkvaudiosubtitlechanger --library "X:/Files" --attribute-config eng:ger eng:OFF`
 
-1. Extract downloaded archive
-2. Copy `config-template.yaml` to `config.yaml`
-3. Update `config.yaml` to fit your needs
-4. Open terminal / cmd in the directory of the jar and the config file 
-5. Execute following commands:
-   1. (Optional) `java -jar mkvaudiosubtitleschanger.jar -l [path to mkv or dir with mkv] --safe-mode`
-   2. To permanently apply changes: `java -jar mkvaudiosubtitleschanger.jar -l [path to mkv or dir with mkv]`
+### Safe usage (best for testing before applying to whole library)
+Portable: `java -jar mkvaudiosubtitlechanger-<version>.jar --library "X:/Files" --attribute-config eng:ger eng:OFF --safe-mode`
+Windows & Linux (installed): `mkvaudiosubtitlechanger --library "X:/Files" --attribute-config eng:ger eng:OFF --safe-mode`
 
-### Configuration
+**Attribute-config must be entered in pairs: `audio:subtitle`; Example: `jpn:eng`. More about this topic
+[here](https://github.com/RatzzFatzz/MKVAudioSubtitleChanger/wiki/Attribute-Config).**
 
-Config file needs to be placed in the same directory as the jar or path to config has to be passed via command line
-argument.
-
-The list of language configurations can be expanded. Use `OFF` if you want to turn of the audio or subtitle lane. 
-Players probably will display forced subtitles nonetheless.
-```yaml
-config:
-  1:
-    audio: ger
-    subtitle: OFF
-  2:
-    audio: eng
-    subtitle: ger
+## Available parameters
 ```
-Subtitle lanes recognized as forced will be set as one. Already existing ones will not be overwritten or changed.
-
-
-### Additional arameters
-These properties overwrite already existing values in the config file.
