 # pixwerx
 
-pixwerx is an opinionated, academic approach to a 3D graphics engine. It mixes
-modern and proven methods to build a fast and portable graphics system.
+pixwerx is a general purpose 3D engine written in C++23 and scriptable with Lua.
 
-## Design Principles
-
-Dogfooding: pixwerx is built on the principle of dogfooding. The engine is a
-full-stack system that tries to implement all necessary functions. The engine
-editor is just a UI build with the engine.
-
-Reasonable dependencies: like many engines pixwerx tries to include as much 3rd-party code as possible and implements some of the core systems itself.
-
-No premature optimization: pixwerx implements only very few systems with machine code. It tries to utilize the power of the compiler as much as possible.
-
-Computer graphics 101: pixwerx does implement graphics components and systems in a  way that makes code portable and not over-parameterized. Usability is
-achieved through layers on top of the core components.
+## Principles
 
+-   datadriven design
+-   multiple platform capable through heavy usage of STL
+-   minimal set of dependencies
+-   efficiency through meta-meta programming techniques
+-   no CPU intrinsics
