 ## Basic Syntax
 ### Difference from Python
 There are some notable differences between luisa_lang and Python:
-- Variables have value semantics by default. Use `inout` to indicate that an argument that is passed by reference.
+- Variables have value semantics by default. Use `byref` to indicate that an argument that is passed by reference.
 - Generic functions and structs are implemented via monomorphization (a.k.a instantiation) at compile time rather than via type erasure.
 - Overloading subscript operator and attribute access is different from Python. Only `__getitem__` and `__getattr__` are needed, which returns a local reference.
