+## Why?
+
+I did this mainly to learn more about how WebGL works, as a continuation of [schattenspiel](https://github.com/felixroos/schattenspiel).
+The hydra DSL seemed to be a good fit to implement with my graph compiler [@kabelsalat/core](https://github.com/felixroos/kabelsalat/tree/main/packages/core).
+Also, it seemed like a nice challenge to try to do this in a single HTML file, which is very sharable and readable / editable.

 ## Completeness
 
-Not all hydra functions / features work, and probably never will, as this is mostly an experiment out of curiosity.
-The initial goal was to see if @kabelsalat/core could be used to compile an existing DSL that also targets another language (GLSL) + another domain (visual). It seems to work out nicely for the moment.
+All [documented](https://hydra.ojack.xyz/api/) hydra functions / features work, except the external sources and some synth settings.
