 ## Executor message builder
 
+Sylvia defines the [`ExecutorBuilder`]() type, which can be accessed through [`Remote::executor`]().
+It's generic over the contract type and exposes execute methods from the
+contract and every interface implemented on it through an auto-generated `Executor` traits.
 Execute messages of other contracts can be built with `Remote` as well by
 calling `executor` method. It returns a message builder that implements

+Methods defined in the `Executor` traits constructs an execute message,
+which variant corresponds to the method name.
+The message is then wrapped in the `WasmMsg`, and returned once [`ExecutorBuilder::build()`]
+method is called.
