+## Introduction
 
-### Introduction
+This CLI tool uses MKVToolNix to quickly modify track properties in MKV files without reencoding. Use profiles to set default audio/subtitle tracks and add commentary, hearing impaired, and forced flags in bulk.
+![](example.gif)
 
-This program helps to change audio and subtitle lines of mkv files.
+## Requirements
 
-### Requirements
-
- - Java 11 or higher
+ - Java 21 or newer
  - mkvtoolnix installation
  
-### Running
-
-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]`
-
-### 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
+## Execution
+```shell
+# Portable
+java -jar mkvaudiosubtitlechanger.jar --attribute-config eng:ger -s ./videos
+# Installed
+mkvaudiosubtitlechanger.jar --attribute-config eng:ger -s ./videos
 ```
-Subtitle lanes recognized as forced will be set as one. Already existing ones will not be overwritten or changed.
+Remove `--safemode` or `-s` to actually apply the changes. Using safemode for the first execution is recommended.
 
+### Update defaults
+To update the default flag for tracks use `--attribute-config` or `-a`.
+This parameter takes in a list of pairs `audio:subtitle` (E.g. `eng:ger`).
+The order of these configs matters, because they are processed in order. 
+The matching stops when the first match was found or when no match was found. 
+For example `-a ger:OFF eng:ger` first tries to find a match for german audio, if that is not possible it tries the same for english with german subs. 
+This can be extended indefinitely.
 
-### Additional arameters
-These properties overwrite already existing values in the config file.
-```properties
- -c,--config <arg>                Path to config file
- -e,--exclude-directories <arg>   Directories to be excluded, combines with config file
- -h,--help                        "for help this is" - Yoda
- -i,--include-pattern <arg>       Include files matching pattern
- -k,--forcedKeywords <arg>        Additional keywords to identify forced tracks, combines with config file
- -l,--library <arg>               Path to library
- -m,--mkvtoolnix <arg>            Path to mkv tool nix installation
- -s,--safe-mode                   Test run (no files will be changes)
- -t,--threads <arg>               thread count (default: 2)
- -v,--version                     Display version
+Using this parameter is not required, but it is the reason I originally started developing this tool.
+
+### Available parameters
+```
+  -a, --attribute-config=<attributeConfig>...
