 Because `error` is a reserved word in Zig, these functions have been renamed to `raiseError` and `raiseErrorAux` respectively.

-These functions have been combined into `Lua.toString()`. The function `lua_tostring` is a macro around `lua_tolstring` and does not return the length of the string.
+The "string" variant functions vs the "lstring" functions only differ by returning the length of the string. In ziglua, the lstring functions are all named "bytes" instead. For example, `lua_tolstring` is `Lua.toBytes`. This is because these functions are typically used in cases when the string _might_ contain zeros before the null-terminating zero.
+
+The "string" variant functions are safe to use when the string is known to be null terminated without inner zeros.

 ## Status
 
-All functions, types, and constants in the public Lua API have been wrapped in Zig **(268/268 identifiers)**.
+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`).
 
-All of the functions have been referenced in tests, so the parameters are correctly typed.
-
-But I am still going through each function to decide the correct return types, errors, parameters, naming, etc.

-ziglua should be relatively stable and safe to use now, but is still rapidly changing.
+All functions have been type checked, but only the standard C API has been tested fully. ziglua should be relatively stable and safe to use now, but is still new and changing frequently.
