 This plugin automatically adds `@types/` packages into your dependencies when you add a package that's covered by one.
 
-This is a crude implementation so far (an ideal implementation should use `preferInteractive` in order to ask the user for confirmation), but it gives an idea of how hooks work. Help appreciated!

 ## Usage
 
 Since Yarn doesn't support dynamic linking yet, you must clone this repository and generate a bundle manually:
 
 ```
-$ yarn build:cli --plugin @berry/typescript
+$ yarn build:cli --plugin @berry/plugin-typescript
 ```
 
 Then put the generated file (`packages/berry-cli/bin/berry.js`) into your project. You can easily try it out by running `yarn add lodash` somewhere:
