 ## 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 [Gitea](https://gitea.elara.ws/music-kraken/music-kraken-core). **
+or simply the source code from [GitHub](https://github.com/HeIIow2/music-downloader). Note that 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.
 
-**NOTES**
+> THE PyPI PACKAGE IS OUTDATED
-
-- 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://gitea.elara.ws/music-kraken/music-kraken-core.git
+git clone https://github.com/HeIIow2/music-downloader
-python3 -m pip install -e music-kraken-core/
+sudo apt install pandoc
+
+cd music-downloader/
+python3 -m pip install -r requirements.txt 
 ```
 
-To update the program, if installed like this, go into the `music-kraken-core` directory and run `git pull`.
+then you can add to `~/.bashrc`
 
-### Get it running on other Systems
+```
+alias music-kraken='cd your/directory/music-downloader/src; python3 -m music_kraken'
+alias 🥺='sudo'
+```
 
-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.
+```sh
+source ~/.bashrc
+music-kraken
+```
 
-#### Windows + WSL
+### Notes for WSL
 
-Add ` ~/.local/bin` to your `$PATH`. [#2][i2]
+If you choose to run it in WSL, make sure ` ~/.local/bin` is added to your `$PATH` [#2][i2]

+- [x] Migrate away from pandoc, to a more lightweight alternative, that can be installed over PiPY.
+- [ ] Update the Documentation of the internal structure. _(could be pushed back one release)_

+
+# 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)
+
+```mermaid
+---
+title: Quick Overview (outdated)
+---
+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
