 ## Installation
 
 You can find and get this project from either [PyPI](https://pypi.org/project/music-kraken/) as a Python-Package,
-or simply the source code from [GitHub](https://github.com/HeIIow2/music-downloader). Note that even though
+or simply the source code from [Gitea](https://gitea.elara.ws/music-kraken/music-kraken-core). **
-everything **SHOULD** work cross-platform, I have only tested it on Ubuntu.
-If you enjoy this project, feel free to give it a star on GitHub.
 
-> THE PyPI PACKAGE IS OUTDATED
+**NOTES**
+
+- Even though everything **SHOULD** work cross-platform, I have  only tested it on Ubuntu.  
+- If you enjoy this project, feel free to give it a star on GitHub.
 
 ### From source
 
-if you use Debian or Ubuntu:
-
 ```sh
-git clone https://github.com/HeIIow2/music-downloader
+git clone https://gitea.elara.ws/music-kraken/music-kraken-core.git
-sudo apt install pandoc
+python3 -m pip install -e music-kraken-core/
-
-cd music-downloader/
-python3 -m pip install -r requirements.txt 
 ```
 
-then you can add to `~/.bashrc`
+To update the program, if installed like this, go into the `music-kraken-core` directory and run `git pull`.
 
-```
+### Get it running on other Systems
-alias music-kraken='cd your/directory/music-downloader/src; python3 -m music_kraken'
-alias 🥺='sudo'
-```
 
-```sh
+Here are the collected issues, that are related to running the program on different systems. If you have any issues, feel free to open a new one.
-source ~/.bashrc
-music-kraken
-```
 
-### Notes for WSL
+#### Windows + WSL
 
-If you choose to run it in WSL, make sure ` ~/.local/bin` is added to your `$PATH` [#2][i2]

-# Programming Interface / Use as Library
-
-This application is $100\%$ centered around Data. Thus, the most important thing for working with musik kraken is, to understand how I structured the data.  
-
-## Quick Overview
-
-- explanation of the [Data Model](#data-model)
-- how to use the [Data Objects](#data-objects)
-- further Dokumentation of _hopefully_ [most relevant classes](documentation/objects.md)
-- the [old implementation](documentation/old_implementation.md)

-sequenceDiagram
-
-participant pg as Page (eg. YouTube, MB, Musify, ...)
-participant obj as DataObjects (eg. Song, Artist, ...)
-participant db as DataBase
-
-obj ->> db: write
-db ->> obj: read
-
-pg -> obj: find a source for any page, for object.
-obj -> pg: add more detailed data from according page.
-obj -> pg: if available download audio to target.
-```
-
-## Data Model
-
-The Data Structure, that the whole programm is built on looks as follows:
-
-```mermaid
----
-title: Music Data
----
-erDiagram
-
-
-
-Target {
-
-}
-
-Lyrics {
-
-}
-
-Song {
-
-}
-
-Album {
-
-}
-
-Artist {
-
-}
-
-Label {
-
-}
-
-Source {
-
-}
-
-Source }o--|| Song : ""
-Source }o--|| Lyrics : ""
-Source }o--|| Album : ""
-Source }o--|| Artist : ""
-Source }o--|| Label : ""
-
-Song }o--o{ Album : AlbumSong
-Album }o--o{ Artist : ArtistAlbum
-Song }o--o{ Artist : "ArtistSong (features)"
-
-Label }o--o{ Album : LabelAlbum
-Label }o--o{ Artist : LabelSong
-
-Song ||--o{ Lyrics : ""
-Song ||--o{ Target : ""
-```
-
-Ok now this **WILL** look intimidating, thus I break it down quickly.  
-*That is also the reason I didn't add all Attributes here.*
-
-The most important Entities are:
-
-- Song
-- Album
-- Artist
-- Label
-
-All of them *(and Lyrics)* can have multiple Sources, and every Source can only Point to one of those Element.
-
-The `Target` Entity represents the location on the hard drive a Song has. One Song can have multiple download Locations.
-
-The `Lyrics` Entity simply represents the Lyrics of each Song. One Song can have multiple Lyrics, e.g. Translations.
-
-Here is the simplified Diagramm without only the main Entities.
-
-
-```mermaid
----
-title: simplified Music Data
----
-erDiagram
-
-Song {
-
-}
-
-Album {
-
-}
-
-Artist {
-
-}
-
-Label {
-
-}
-
-Song }o--o{ Album : AlbumSong
-Album }o--o{ Artist : ArtistAlbum
-Song }o--o{ Artist : "ArtistSong (features)"
-
-Label }o--o{ Album : LabelAlbum
-Label }o--o{ Artist : LabelSong
-
-```
-
-Looks way more manageable, doesn't it? 
-
-The reason every relation here is a `n:m` *(many to many)* relation is not, that it makes sense in the aspekt of modeling reality, but to be able to put data from many Sources in the same Data Model.  
-Every Service models Data a bit different, and projecting a one-to-many relationship to a many to many relationship without data loss is easy. The other way around it is basically impossible
-
-## Data Objects
-
-> Not 100% accurate yet and *might* change slightly
-
-### Creation
-
-```python
-# needs to be added
-```
-
-
-
-If you just want to start implementing, then just use the code example I provided, I don't care.  
-For those who don't want any bugs and use it as intended *(which is recommended, cuz I am only one person so there are defs bugs)* continue reading, and read the whole documentation, which may exist in the future xD
