 ## Dependencies
 
 You only need the `drink` library brought into your project:
 
 ```toml
-drink = { version = "0.8" }
+drink = { version = "0.19.0-alpha" }

 For every contract that you want to interact with from your tests, you need to create a _contract bundle_, which includes:
 
-- built contract artifact (`.wasm` file),
+- built contract artifact (`.polkavm` file),
 - contract transcoder (object based on the `.json` file, responsible for translating message arguments and results).
 
 The recommended way is to use `drink::contract_bundle_provider` macro, which will discover all the contract dependencies (including the current crate, if that is the case) and gather all contract bundles into a single registry.
