+It contains two functions, `callContract` and `staticcallContract`, that allow the user to call a Cairo contract or class deployed on
 the Starknet appchain. The method takes three arguments:
 
-- `contractAddress` or `classHash`: The address of the Cairo contract to call /
-  class hash to call
+- `contractAddress` : The address of the Cairo contract to call
 - `functionSelector`: The selector of the function to call, as the `sn_keccak`
   of the entrypoint name: `keccak("entrypoint_name") % 2^250`
-- `data`: The calldata to pass to the Cairo contract, as individual bytes.

 Contract developers can use this library to interact with the Cairo precompiles.
 Let's take an example of a contract that calls a Cairo contract to increment a
