-### Introduction
 
-This program helps to change audio and subtitle lines of mkv files.
+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.
 
-### Requirements
+![](https://github.com/RatzzFatzz/MKVAudioSubtitleChanger/blob/master/example.gif)
 
- - Java 11 or higher
+## Requirements
+
+ - Java 21 or newer
  - mkvtoolnix installation
  
-### Running
+## Execution
-
+Portable: 
-1. Extract downloaded archive
+```
-2. Copy `config-template.yaml` to `config.yaml`
+java -jar mkvaudiosubtitlechanger-<version>.jar --library "X:/Files" --attribute-config eng:ger eng:OFF
-3. Update `config.yaml` to fit your needs
+```
-4. Open terminal / cmd in the directory of the jar and the config file 
+Windows & Linux (installed): 
-5. Execute following commands:
+```
-   1. (Optional) `java -jar mkvaudiosubtitleschanger.jar -l [path to mkv or dir with mkv] --safe-mode`
+mkvaudiosubtitlechanger --library "X:/Files" --attribute-config eng:ger eng:OFF
-   2. To permanently apply changes: `java -jar mkvaudiosubtitleschanger.jar -l [path to mkv or dir with mkv]`
-
-### Configuration
-
-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
 ```
-Subtitle lanes recognized as forced will be set as one. Already existing ones will not be overwritten or changed.
 
+Add `--safe-mode` oder `-s` to not change any files. This is recommended for the first executions.
 
-### Additional arameters
+Attribute-config must be entered in pairs: `audio:subtitle`; Example: `jpn:eng`. More about this topic
-These properties overwrite already existing values in the config file.
+[here](https://github.com/RatzzFatzz/MKVAudioSubtitleChanger/wiki/Attribute-Config).
-```properties
+
- -c,--config <arg>                Path to config file

+                              and update files accordingly (e.g. jpn:eng jpn:
- -l,--library <arg>               Path to library
