 While there are some helper functions added to complement the C API, Ziglua aims to remain low-level. This allows full access to the Lua API through a layer of Zig's improvements over C.
 
-If you want something higher-level (but doesn't expose the full API), perhaps try [zoltan](https://github.com/ranciere/zoltan).

-## Status
-
-Nearly all functions, types, and constants in the C API have been wrapped in Ziglua. Only a few exceptions have been made when the function doesn't make sense in Zig (like functions using `va_list`).
-
-Nearly all functions have associated Zig tests. Ziglua should be relatively stable and safe to use now, but I am still polishing things and function signatures may change from time to time.
