 ### Added
 * Introduces an entire suite of helpers to assist with interacting with smart contracts ([#929](https://github.com/stellar/js-stellar-sdk/pull/929)):
-  - `ContractClient`: generate a class from the contract specification where each contract method gets included with a "JSified" name. Each method returns an `AssembledTransaction` that can be used to modify, simulate, decode results, and possibly sign, & submit the transaction.
+  - `ContractClient`: generate a class from the contract specification where each Rust contract method gets a matching method in this class. Each method returns an `AssembledTransaction` that can be used to modify, simulate, decode results, and possibly sign, & submit the transaction.
   - `AssembledTransaction`: used to wrap a transaction-under-construction and provide high-level interfaces to the most common workflows, while still providing access to low-level transaction manipulation.
   - `SentTransaction`: transaction sent to the Soroban network, in two steps - initial submission and waiting for it to finalize to get the result (retried with exponential backoff)
