-# ParadiSO - eine minimale 2D-Grafikengine
-
-**ParadiSO** wurde als stark abgespeckte 2D-Version meiner `pixwerx`-Engine konzipiert. _ParadiSO_ verfolgt einen minimalistischen Ansatz für 2D-Grafik zu Bildungszwecken. Es verwendet modernes C++ und ein datengetriebenes Design, jedoch keine ECS (Entity Component System).
-
-## Bildungszwecke
-
-Einige Argumente für seinen Bildungsaspekt:
-
--   Kombination verschiedener Konzepte und Paradigmen zur Erstellung ausdrucksstarker, aber knappen Codes
--   Stark von Rust-Code inspiriert
--   Für den mathematischen Code wird eine sofortige Auswertung verwendet (keine Expression-Templates), jedoch mit der Verwendung von `constexpr`, um eventuelle Performance-Overheads auszugleichen und optimale Vektorisierung zu erreichen.
--   Versteckt alte `C`-APIs hinter einer modernisierten Fassade
--   Es lehnt sich stark an die STL und ihre Algorithmen an
-
-## Minimalistisch
-
-Da diese Engine einige Muster und Designkonzepte zeigen soll, versucht sie, unnötigen Ballast zu vermeiden.
-
-## Abhängigkeiten
-
-ParadiSO wird mit den notwendigen Komponenten geliefert. Diese sollte jedoch hier erwähnt werden:
-
--   [GLFW 3.3.8](https://github.com/glfw/glfw)
--   [GLAD](https://github.com/Dav1dde/glad)
--   [STB image](https://github.com/nothings/stb)
-
-## Toolchains
-
-ParadiSO kann auf verschiedenen Plattformen gebaut werden
-
--   Windows (Visual Studio Build Tools 2022)
--   MacOS (clang 14 or later)
--   Linux (clang 14 or later, gcc 13.2.1)
-
-Andere Kombinationen sind möglich aber nicht getestet.

-# Todo
-
-Here some ideas for improving this tiny engine:
-
-## Rendering
-- [ ] replace the OpenGL renderer with a Vulkan backend
-- [ ] add animatable sprites (access to UV mapping and tiling)
-- [ ] add a SDF based renderer (parametric tiles and font rendering)
-
-## Game Support
-- [ ] audio!
-- [ ] some minimal animation system with tweening with different f-curves
-
-
-## System Level
-
-- [ ] add a `Asset` handler to load cache and manage assets
-- [ ] introspection of file system if we load assset
-
-## Design
-
-- [ ] replace some of the 'unkown source' assets
-
-## Build / Dev Support
-- [ ] add a test rig either with Snitch or Catch2
-- [ ] write some reasonable testcases
-- [ ] add CPU and GPU benchmarks to address various issues
