 ### Define Your Computation
 
-User computation must be defined as **a function** using ZKStats operations and PyTorch functions. The function signature must be `Callable[[State, dict[str, torch.Tensor]], torch.Tensor]`:
-
-```python
-import torch
-
-from zkstats.computation import State, Args
-
-# User-defined computation
-def user_computation(state: State, args: Args) -> torch.Tensor:
-    # Define your computation here
-    ...

+User computation must be defined as **a function** using ZKStats operations and PyTorch functions. The function signature must be `Callable[[State, Args], torch.Tensor]`:
 - first argument is a `State` object, which contains the statistical functions that ZKStats supports.
-- second argument is a list of PyTorch tensors, the input data. `data[0]` is the first column, `data[1]` is the second column, and so on.
+- second argument is a `Args` object, which is a dictionary of PyTorch tensors, the input data. `Args['column1']` is the first column, `Args['column2']` is the second column, and so on.
 
 For example, we have two columns of data and we want to compute the mean of the medians of the two columns:
