@@ -218,20 +218,60 @@ The **msg** module in file `msg.rs` typically defines the messages and queries t
 contract accepts and responds to. Messages are usually structured as Rust enums or structs and
 define the input and output interfaces of the contract. In our example this includes:
 
-- **`CounterInitMsg{:rust}`** enumeration, used to initialize the contract.
-  `CounterInitMsg::Zero{:rust}` variant initializes the counter with zero value, and
-  `CounterInitMsg::Set{:rust}` variant initializes the counter with an arbitrary value in range 0
-  to 255. This message is passed to `instantiate{:rust}` entry-point of the counter smart contract.
-- **`CounterActionMsg{:rust}`** enumeration, used to perform various actions within the contract,
-  especially incrementing (the `CounterActionMsg::Inc{:rust}` variant), decrementing (the
-  `CounterActionMsg::Dec{:rust}` variant) and setting an arbitrary counter value (the
-  `CounterActionMsg::Set{:rust}` variant). This message is passed to `execute{:rust}` entry-point of
-  the counter smart contract.
-- **`CounterQuery{:rust}`** enumeration, with its single variant `CounterQuery::Value{:rust}`, used
-  to query the state of the contract, in our case to retrieve the current counter value. This
-  message is passed to `query{:rust}` entry-point of the counter smart contract.
-- **`CounterResponse{:rust}`** struct with single field `value{:rust}`, used to pass the responses
-  (results) to queries.

 Overall, this `msg.rs` file is basically setting up the contract’s _social skills_, defining how it
 interacts with the outside world by initializing, taking actions, and answering questions. Each
